[Plugin: WordPress Advanced Ticket System] Errors when creating new ticket

Hi,

When creating a new ticket after a fresh install of the free version I receive the following error messages at the top of the new ticket page.

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘wats_insert_post_data’ was given in /var/…/htdocs/wp-includes/plugin.php on line 170

Any ideas as to what I could check?

Cheers
