Version 1.5.5 is giving warning message – should I be worried?

Hi I am getting the same error after upgrade:

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 /home/gfesport/public_html/wp-includes/plugin.php on line 429

Also getting this:

Warning: Cannot modify header information – headers already sent by (output started at /home/gfesport/public_html/wp-includes/plugin.php:429) in /home/gfesport/public_html/wp-includes/pluggable.php on line 899

me too:
‘Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘WP_Collapse_O_Matic::admin_init’ was given in /home/elatedco/public_html/wp-includes/plugin.php on line 429′

I’ve disabled it, but need it back please!

Issue is fixed with 1.5.6
We also fired the drunken pirate monkey that is suppose to test code before it’s published.

Thanks for your Support, Baden. You earned an upgrade. I’m going Pro…. Hi Five!

Much obliged Baden

Great service -as ever!

very happy it worked out!
don’t forget to vote for pedro!

Hi Baden.

Thanks for getting back to us so quickly. I just activated and unfortunately still getting an error

‘Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘WP_Collapse_O_Matic::admin_init’ was given in /home/elatedco/public_html/wp-includes/plugin.php on line 429′

Thanks!
Karen

oops, forgot to update it. Duh I feel like an idiot now!

Thanks!

I have the Version 1.5.6 end stil have the eror… https://www.bisericadunamis.ro/
I disabled the plugin for a moment, as the error remains … I’m confusing.

Bucur,

Please completely de-install the plugin and re-install it from the wordpress repo. If that dose not solve the issue, let us know and we’ll take a closer peek.

if that does not work for you, then please try updating to version 1.5.7a direct from the plugin oven: https://plugins.twinpictures.de/plugins/collapse-o-matic/

1.5.7.a no reaction for me. Looks like I ruined churches website. If I’d not update plugin… I’am not a expert php. What am I doing now?

Bucur: Send an email to: info [at] twinpictures [dot] de and we’ll get you squared away. There must me a simple reason why things are not working… and we want you to get back up and running soon as possible.

Problem solved, the error code was in header.php.
