Greetings,

This is now showing up in my error_log and I don't know what plugin it's for or how to exactly fix it.

PHP Warning:  preg_replace_callback(): Requires argument 2, 'stripslashes('\1').mb_convert_case(stripslashes('\3'),MB_CASE_UPPER, 'UTF-8')', to be a valid
callback in /home1/patsworl/public_html/f-106deltadart/piwigo/include/smarty/libs/plugins/modifier.capitalize.php on line 43

Help??
