FYI
phpinfo says
php ver 4.4.9
open_basedir /home/(edited:myuserrefhere)/:/tmp:/usr/local/lib/php
Ah - looks like its a combinations of things
according to my supplier
PHP open_basedir setting for this particular url needs to be set to "no value"
or
use a more up to date version of FCK, which resolves the problem
Can you guys confirm this is the case?
