Missing argument 2 for wpdb::prepare()

Hi there,

Since I upgraded to 3.5 I am getting this error: Missing argument 2 for wpdb::prepare()

and I think this line that is the culprit but I cannot find anyone else that has this exact issue in this forum:

<strong>$th_vers = $wpdb->get_var( $wpdb->prepare( "SELECT th_vers FROM $table WHERE id = 1 LIMIT 0,1" ) );</strong>

Because I this error I now cannot edit information to exiting items on my website. Not a plugin issue, already tested the plugins.

Any help with fixing the code would be greatly appreciated as my developer no longer supports my theme does not offer email support.

Thank you!
