Troubleshooting Web4m Conference System:

General Tip #1

Try using Firefox as your browser. Not only is it safer it is also more reliable as a browser than Internet Explorer. It is a standard web practice to have more than one browser to try for when web pages are not cooperating. Firefox is free and dependable.

General Tip #2

Since the conference system is a Java applet make sure that you have the most current version of Java installed on your computer.

If you are using a MAC Firefox and Internet Explorer may not allow you to log in. JDH (Developers of Web4m) recommend the Sarfari Browser for MAC users. I have seen students use Sarfari successfully.

Since the web is not a static environment, you should expect to encounter some problems now and then. Here are a few of the most common problems that occur and what to do to troubleshoot them.

The login screen never apears
No audio with Vista and Internet Explorer
Dual PC/MAC operating system causing no audio
"Lost audio" while you are in a class
Errors reported and no audio when entering a conference in a classroom
No sounds and no errors reported
Sound is too choppy to understand (due to slides):
Sound is too choppy to understand (for no reason):
The instructor has disappeared or is non responsive.
The entire class got booted from the classroom and can't get back in, but still has internet access.

If you notice some else is having audio problems in the class, please use the chat bar to offer your assistance, and help them troubleshoot the problem. Because time is limited, the instructor will not be able to stop the lecture and address each of these issues in class. Please feel free to paraphrase what the instructor is saying in the chat box if someone loses audio. You may do this even if no one looses audio as a good way to reinforce learning. Don't be concerned if you cannot resolve the issue immediately. Each class is recorded so you can view it at you convenience.

When I click on the link 'log into class' the window to run in the background pops up, but the log in screen never does.

This is normally caused by a problem with Java. Simply go to the Java site and reinstall the program.

No audio with Vista and Internet Explorer

The reason that audio does not work is because the Web-4M installs a little audio tool that needs to run. Internet Explorer is running in “Protected Mode”, so it doesn’t have access to open that audio tool.
If you have Internet Explorer in your Quick Launch bar (right by the start menu) follow these steps:

  1. Right-click on the Internet Explorer icon.
  2. Click “Run as Administrator”.
  3. Go to http://conference.classicalfree.com/JDHHTML/ClassicalFreeRS.html in that browser window.

If you don't have Internet Explorr in your Quick Launch bar follow these steps:

  1. Click on the Start Menu.
  2. Type “internet explorer”.
  3. Right-click on “Internet Explorer”.
  4. Click on “Run as Administrator”.N
  5. Now, Go to or paste the following link into the address bar: http://conference.classicalfree.com/JDHHTML/ClassicalFreeRS.html

The audio should work now. (You will still have the normal firewall problems)

The login screen never apears

Normally the most current version of Firefox resolves all audio and login problems. (Compare the version number of the latest free download on the Firefox site www.mozilla.com/firefox/ with the version number under the help/about option in your broswer menu bar.) Firefox normally has the most seemless itergration with Java (the conference system is a Java applet.) However, sometimes Java updates it's software and may create a problem for Firefox or some of the other browsers (they will eventually address the issue with an update of their own, or Java will issue another update.) Until that time you may have to use Internet Explorer. Currently, for audio to work with Internet Explorer on Vista operating systems you must right click on the Internet Explorer and then select "run as administrator".

Dual PC/MAC operating system causing no audio

For the Intel PC/Mac (MACBOOK PRO -- the dual operating system ) and students have tried to install on the PC side but we never were able to get sound. JDH says that they have not tested with the dual PC/Mac and it may not work properly. Try using Sarfari on the MAC side or running Internet Explorer as administrator on the PC side.

"Lost audio" while you are in a class

Lost audio problems are the most common. The most important thing to remember is to relax when you experience an audio problem. Often they come and go like the wind and will improve in a matter of minutes, so the first troubleshooting step is waiting for a few minutes. Remember that you can always replay the full lectures with all audio and visual components, so there is no need to worry that might miss something vital. Feel free to mention that you have lost audio in the chat window. (@ is the symbol we use to communicate that you cannot hear.) You can also ask someone to type notes of what is being said while your computer is recovering from this problem.

Errors reported and no audio when entering a conference in a classroom:

Some firewalls will not allow the sound .exe file to talk to the server. This will generate errors and disable all audio.

Test to see if it is firewall issue by closing your browser and turning off your firewall then log into the class again. (Remember to turn your firewall back on after this test.) If you now have audio capablities you know that your firewall was the problem. Try each of the following possible rememdies to fix the problem.

Possible steps to fix this problem (Try each to see if your firewall has these options and if any fix the problem):

  1. In your firewall permit and/or set the web site www.classicalfree.com to "trusted" in your firewall.
  2. Permit the sound .exe file to access the web AND select always permit.
  3. If you are using a Norton Firewall, have permitted the sound .exe file (and have selected the always permit box), and still receive these errors. Exit the conference (and possibly room) and then re-enter. If you selected the always permit box in the Norton pop-up you won't see the issue again in this session, and should have audio capabilities.

No sounds and no errors reported:

  1. First wait for a couple minutes to see if it improves.
  2. Check the basics. Put an audio CD or something in your computer to make sure that your speakers are plugged in, turned on, and turned up.
  3. If your speakers work fine in other applications, then it could be a bump due to; high internet traffic, local server difficulties (these are becoming more common with the increasing number of internet use and viruses, worms, etc.,), or local computer processing difficulties.
  4. If the problem persists use the following procedures in the order given to try to fix the problem.
  5. Try exiting the conference and returning to see if that helps.
  6. Try exiting the conference and then exiting the classroom. Then return (Be sure to wait for numbers to appear next to the list of rooms before selecting a room.) to see if that helps.
  7. Ask someone from the class to test the online phone with you.
    • Exit the conference and classroom with someone (This will not work if either person is in a classroom.)
    • In the "svserver" window highlight the person's user name. Then press "phone" from the left sidebar. The other person should "answer" the call and you should be able to talk (full duplexing - no passing a mic back and forth). If the audio works, hang-up and try going back to the classroom.
    • If the audio still doesn't work, quit the entire program and reload and email the instructor.
    • You may also call JDH Technologies at (757) 873-4747, or email them at info@jdhtech.com. Please mention that you are with Classical Free Tutorials (that is who we rent our classroom from).

Sound is too choppy to understand (due to slides):

If the instructor has loaded slides to be used on the whiteboard in class, you will see a list of these slides in a special window below the participating window. Next to the names of the slides there are diamonds, which should be turning yellow and then green. If any are not green, your computer is downloading those files and that is disrupting the audio.Do not exit the conference. Turn down your speakers and wait for the slides to finish loading. After they all are green, turn up your speakers and see if the sound is clear.

Sound is too choppy to understand (for no reason):

This bump could be due to; high internet traffic, local server difficulties (these are becoming more common with the increasing number of internet use and viruses, worms, etc.,), or local computer processing difficulties and the speaker's or listener's end. Use the following procedures in the order given to try to fix the problem.

  1. Exit other programs running on your computer.
  2. Try exiting the conference and returning to see if that helps.
  3. Try exiting the conference and then exiting the classroom. Then return (Be sure to wait for numbers to appear next to the list of rooms before selecting a room.) to see if that helps.
  4. Ask someone from the class to test the online phone with you.
    • Exit the conference and classroom with someone (This will not work if either person is in a classroom.)
    • In the "svserver" window highlight the person's user name. Then press "phone" from the left sidebar. The other person should "answer" the call and you should be able to talk (full duplexing - no passing a mic back and forth). If the audio works, hang-up and try going back to the classroom.
    • If the audio still doesn't work, quit the entire program and reload and email the instructor.

The instructor has disappeared or is non responsive.

  1. Watch your email. If the instructor still has a connection he will eventually send an explanatory email and further instructions. You can also check the forum to see if he has posted anything there.
  2. Sometimes the local ISP goes down. This would make it impossible for him to send email or use the forum. In such a situation, the instructor will find some student who can receive telephone calls as well as be online. He will try to get word to the class through such a student who will relay the message in the classroom.
  3. If fifteen minutes have passed without communication from the instructor consider the class cancelled. Further instructions will eventually be sent via email and posted on the forum.

The entire class got booted from the classroom and can't get back in, but still has internet access.

1. In this situation, we will all meet in the forum on BiblicalGreek.org.
