CMS Made Simple Forums

When using the TinyMCE that came with the deployment I get an "Internal Server Error" When clicking the browse button on the image edit/insert popup. I've tried getting the FCKEditor image upload working but it gave a strange xml error. The image manager for CMSms works fine however. I followed all the install instructions.

What can I do to get an editor with a working image upload integrated into CMSms?

It's hard to tell what's going on without more information on the error, but this seems to happen more often
(see this and this post for example)

Which versions of CMS Made Simple and the TinyMCE module are you using?

Do you have access to your server's error log?
Any messages?
