# SQL Failures/Volume Optimization

 * I host two moderate volume blogs (1200 daily visitors each) that are causing 
   major SQL or CPU issues that keep taking my server down.
 * Both sites have this error:
 * Warning: Invalid argument supplied for foreach() in /home/femme/public_html/wp-
   includes/classes.php on line 1547
 * The sites are [DailyDoseofQueer.com](http://www.dailydoseofqueer.com) and [JenBurke.com](http://www.JenBurke.com).
 * Both sites are running Angsuman’s Translator Pro plugin – back in February, we
   added WP-Cache to speed things up as the sites were consuming lots of server 
   resources without any good reason we could find.
 * Now, after a month or so of good behavior, they’re both causing the same issues,
   and worse, I can’t access wordpress to try turning plugins off to see if it would
   make a difference.
 * Does anyone have any suggestions for how I can get to the root of the issue here?
