Hi guys
I am a bit stuck. Since trying to carry out the automatic upgrade to 3.6 my site threw the following error:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, '_show_post_preview' was given in /websites/123reg/LinuxPackage21/an/ne/tt/annettenix.com/public_html/adminarea/wp-includes/plugin.php on line 406
The theme is called Craft from ThemeTrust.
I had a look at plugin.php but couldn't see anything obvious, any thoughts?
Thanks,
Ian
