Site redirect / plugin error (2 posts)

    Hello. A while ago I developed this site curlyproductions.co.uk

    The owner recently bought a new domain and had his IT guys copy the content to it:

    There is now an error:
    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function '_show_post_preview' not found or invalid function name in /var/sites/o/onlinevideoproduction.co.uk/public_html/wp-includes/plugin.php on line 406

    As you can see, all the links and content come from the original domain.

    Any ideas what's going on? It's using the latest WordPress version.

    I have quite a few plugins so would like to avoid having to go through and deactivate them if possible. I've tried changing the theme and got the same error.
