After Update I got a white wp-admin. I switched to another theme and after that, back to the child theme.
But there is still an error (Logfile for fastcgi):
[05-Jul-2015 10:56:18 UTC] WordPress-Datenbank-Fehler You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘) LIMIT 1’ at line 1 für Abfrage SELECT user_id FROM wp_usermeta WHERE meta_key = ‘pmproup_user_page’ AND meta_value IN() LIMIT 1 von require(‘C:\inetpub\wwwroot\sexy-ladies\wp-blog-header.php’), wp, WP->main, do_action_ref_array, call_user_func_array, pmproup_wp
May you can help?
