I changed some options at NextGen Gallery and now I've this problem: Every time I try to edit or create a post or page I get a page with the following message:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'searchnggallerytags' was given in /home/*****/public_html/*****/wp-includes/plugin.php on line 166
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'searchnggallerytags' was given in /home/*****/public_html/*****/wp-includes/plugin.php on line 166
Warning: Cannot modify header information - headers already sent by (output started at /home/*****/public_html/******/wp-includes/plugin.php:166) in /home/*****/public_html/*****/wp-includes/pluggable.php on line 850
For what I remember, the only thing I've changed is the thumb size and checked "Activate related images:". Either way, reseted all option just in case but nothing happened, I still get the same message.
On a side note, the posts are edited and/or created anyway, just getting that message. btw, if I deactivate the plugin it works perfect
Any help on this?
Thanx in advance!
