I'm using Pagelines Framework in a wordpress multisite network. I'm having a lot of log error messages like this:
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /path/wp-includes/plugin.php on line 429, referer: #blogreferer#
Do you know what is causing this error in pagelines framework?
Thanks a lot!
