# Site redirect / plugin error

 * 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:
    [http://onlinevideoproduction.co.uk/](http://onlinevideoproduction.co.uk/)
 * 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.
 * Thanks!
