Ensure that '<tt>LSAttachmentPath</tt>' does exist and that it is 
writable by the OGo process!

<p>
Check the <tt>LSAttachmentPath</tt> configuration by executing one of the following commands:
</p>
<pre>
`Defaults read NSGlobalDomain LSAttachmentPath`
`Defaults read OpenGroupware LSAttachmentPath`
</pre>

If OGo can't write the path or including files, it either is missing, the disk is full or the permissions are wrong. Starting OGo as with
<pre>
strace -e open OGo...
</pre>
might help in finding the problem.
