File Cabinet Upload: Warning: shell_exec() has been disabled
 

I have read a lot here and in other forums for fixing my problems with file cabinet upload.

But all tries did not help, so I appreciate every hint!

When I upload an swf file (generated by openoffice impress), I get the message:
Unacceptable file type

The error log says:
Warning: shell_exec() has been disabled for security reasons in /home/maxxinco/public_html/lib/pear/Compat/Function/mime_content_type.php on line 30

So I do not know what to do with that message. In the mime_content_Type.php I can not find a disabled shell_exec .... ?

Any clues?

Thanks a lot.
Dirk.
