    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

    Can you replicate the problem using the default Twenty Thirteen theme with all other plugins deactivated?

    Annoyingly, the default theme was removed. I can’t add a new theme through the site, presumably I could upload Twenty Thirteen via FTP to test it?

    Tried uploading TwentyTen but live preview is showing me:

    Fatal error: Call to undefined function get_post_format_slugs() in /websites/123reg/LinuxPackage21/an/ne/tt/annettenix.com/public_html/adminarea/wp-includes/theme.php on line 1262

    What version of WordPress are you running?

    Why are you using an old copy of WordPress? Were you aware that your site is currently running a very real risk of being hacked? You need to upgrade WordPress asap. by:

    – switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

    – resetting the plugins folder by FTP or phpMyAdmin.

    – re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    – running the upgrade manually via wp-admin/upgrade.php

    That worked perfectly esmi, thanks so much for the suggestion

    (I don’t manage the site, just helping out!)
