Thanks for the tip, Tim. I'm not an expert on this. I'll have to figure out what the 'client' means in this case. I suppose it's something like the php.ini files? Thanks anyway.

Hi Harry, have you seen this page?
http://dev.mysql.com/doc/refman/5.5/en/packet-too-large.html

It appears that the max packet size has to be set at both the client and the server to be effective

For the above config files - did you add it to the [mysqld] or the [mysqld-safe] section? and then restart the service?

Nope. I think I found all the .cnf files already, changed the max_ everywhere but nothing helps.
Support of Clearfoundation doesnt know either.
Funny.

/usr/share/system-mysql/etc/my.cnf?

Thanks for the reply, Tim.
Unfortunately that didn't help.

Hi Harry, try /etc/my.cnf ?
max_allowed_packet=16M

service mysqld restart
