Was getting this error;
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘openhook_post_top_box’ was given in /home/xxxxxx/public_html/wp-includes/plugin.php on line 339
Emailed Rick and he had the bug causing the error fixed and his plugin updated in under 10 minutes. Now that’s service!!
Thanks Rick.
