[Resolved] Version 1.5.5 is giving warning message – should I be worried?
Just installed Collapse-O-Matic version 1.5.5. Everything seems to work fine. But now in Admin, I’m getting the following message at the top of each page:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘WP_Collapse_O_Matic’ does not have a method ‘admin_init’ in /home2/nickwing/public_html/test8/wp-includes/plugin.php on line 429
Should I be concerned by this message?
NB. Regarding the file it refers to: wp-includes/plugin.php. I’ve downloaded a virgin copy of WordPress 3.71 and compared its plugin.php to mine. They are identical.
