 * My host upgraded to PHP 5.5 today, so parts of my site have stopped working 🙁
 * I get errors like this one in a few places:
 * mysql_query(): Access denied for user ‘root’@’pro20.meebox.net’ (using password:
   NO)
 * Most of my site is working, the error is only found in my child theme + two plugins.
 * Any idea how I can fix that?
 * Thanks,
    Mads

 * Your child theme and plugins are using the mysql driver, which is no longer supported
