Annoying error after re-install

I've had to reinstall ISPConfig on a brand new Ubuntu Dapper install (as per the Perfect Setup).

Now, when I log in to ISPConfig on occasion I get a really annoying error in inhalt_tree.php that makes the page continuoisly reload. The error is in line 34 and has to do with "linkFarbe not defined". Any suggestions on where/how I can fix this?

Thanks in advance.

ausgabeFrame.write("<STYLE>\n<!--\nA {text-decoration: none}\nA {color: " + linkFarbe + "}\nA:hover {color: " + aLinkFarbe + "}\nBODY{ scrollbar-arrow-color: white\;\nscrollbar-base-color: #E0E0E0 }\n-->\n</STYLE>\n");

 

Is it maybe related to this thread? http://www.howtoforge.com/forums/showthread.php?t=569&highlight=inhalt_tree.php

Also, if you use Firefox with plugins, it's possible that some plugins interfere with ISPConfig.

 

Hmmm...It definitely looks similar and yes, I run FireFox with a plugin or two. I'm reinstalling (unrelated, stupid user error I made) and will check using IE7 w/out plugins.

 

Don't see the behaviour with FF2.0 and few plugins anymore. Guess it's one of those things that are hard to determine the root cause for...
