Drupal: Wysiwyg TinyMce not working in IE

I recently was developing a Drupal Ver6 site and when doing functionality testing noticed that the TinyMce Editor was not working in IE. The editor buttons would not display. After hours of bug hunting and goggling I finally figured out the problem. IE apparently limits how many css includes you can have, so to resolve the issue I just had to Enable “Optimize Css Files” from the performance tab.

Hope this saves you hours of searching.

I tried your fix, but it didn’t seem to help my situation. I’m having the same problem. Tiny MCE working in Firefox but not IE.

The JS errors I’m receiving are:

Object doesn’t support this property or method
tiny_mce.js Line: 1

Object doesn’t support this property or method
wysiwyg.js Line: 199 Code: 0 Line: 5

Anyone else seeing this in Drupal 6x?

@Seppo: Another issue I have run into that might apply in your situation was, I used a spell check plug-in and that killed my wysiwyg. Try disabling all or most wysiwyg tool bar buttons and see if that solves the problem.

I tried this fix, but it caused a PHP stack overflow that crashed my site.

Thanks, saved me hours there. I normally work in FFox, but the client was using IE, and this is the only little bit not working.

Would have been so much fun trouble shooting this

Ya man … Yeah.

Nicely done.

Unfortunately, it didn’t work for me because the “Optimize Css Files” option is grayed out due to some content access modules that I am using. I had to put all my CSS files together manually. Such a painful task. But it worked.

Thanks a bunch.

Thanks – I was sub-theming ZEN and then noticed that the TinyMCE editor lost buttons in IE but not Chrome / FireFox, but reverting to ZEN theme worked, so figured either I had messed up the CSS for IE or there was some other explanation.
Googled for “tinymce ie buttons” and this was the most likely post – remembered seeing the “install ie_css_optimizer” info on ZEN sub-theming and found further information here http://drupal.org/node/663324
I love the Internet, it really helps when people share their knowledge.
