I am running a joomla 1.5.26 site on a IIS 7.5 server with PHP 5.3.19. When ever I try to edit articles from the front end with IE as my browser, I get a stack overflow error at line 1. When you click ok, the stack overflow error pops up again. I do not get this error with google chrome or firefox. I have changed editors from JCE to TinyMCE and FCKeditor all with the same results.

This site was working wonderfully on a previous version of joomla with PHP 5.2 and K2. We had to upgrade PHP, which forced the upgrade of K2. I have tried to figure this out and I am getting no where. My website users are frustrated as am I.

Can anyone give me some suggestions on what to do to track down this error?
