Turck MMCache Troubleshooting

If you are using Turck MMCache and, in IMP:

• You cannot see any message bodies or attachments OR
• You only see the full text of the headers in the message body
  Here is an example image of the issue:
  

(Also see http://marc.info/?l=imp\&m=108163709627707\&w=2 for example symptoms)

Go here for instructions on how to fix your problem:

Make sure the cache is deleted everytime Apache is restarted:

After some testing I entered the following to my php.ini:
mmcache.filter="!*/lib/Horde/MIME/Message.php*"

Turck MMCache seems to be dead. There's a fork called eAccelerator (http://eaccelerator.sourceforge.net/\). This problem should be fixed in the CVS version, but it is not yet fixed in version 0.9.3.
