Synametrics Technologies

After the most recent update, we are no longer able to use FireFox (33.0.1) to browse files using SynaMan.  Internet Explorer works fine (IE version: 11.0.9600.17280, IE Update: 11.0.12).  I am using the exact same user in both browsers (IE works, FireFox does not).  I have also tried multiple users and they all produce the same results.  This was working with FireFox yesterday and it does not work today.  The only thing I know of that changed was the update that was done automatically last night.  I also did try to reboot the server after the update, but it did not resolve the issue.

When attempting to use the "explore" tab after logging in, the following errors are received:

Error 1: "Communication error occurred. Try reconnecting to the remote machine. - ERROR: 500 The call failed on the server; see server log for details"

Error 2: "Communication error occurred. Try reconnecting to the remote machine. - ERROR: com.google.gwt.user.client.rpc.StatusCodeException: 500 The call failed on the server; see server log for details"

Clicking "OK" on both of these error messages displays the normal explore tab, but the "Available Folders" is blank and no files can be seen.

Here are the last two messages in the SynaMan.log file which correspond to the error messages the user receives:

Keith,

Click F5 on your browser to refresh. This is most likely a JavaScript issue. A refresh will most likely cause your browser to fetch new scripts from the server.

Thanks, that did the trick!
