Recently one of my client sites had an issue where the custom theme info was corrupted. The following warnings were being thrown, and the theme wasn't loading:

PHP Error Reporting

Warning: Invalid argument supplied for foreach() in /drupal/path/includes/theme.inc on line 497

Warning: Invalid argument supplied for foreach() in /drupal/path/includes/theme.inc on line 502

Warning: Invalid argument supplied for foreach() in /drupal/path/includes/theme.inc on line 497

Warning: Invalid argument supplied for foreach() in /drupal/path/includes/theme.inc on line 502

Somehow the theme info database record (which holds a PHP serialized object) was corrupted.

The quick fix for this was to switch to a different theme, and switch back (rebuild the theme info). As this was hard to do without navigation, here are the URLs to hit:

baseurl.com/user

baseurl.com/admin/build/themes/select

Select another theme, and switch back to your original one
