Entire VPS locks up when using particular theme [closed]

Usually the first step is to make sure there is no problem by changing the theme to Twenty Eleven and running the ‘same steps’ to recreate the problem.

Some themes may not be ready for WordPress 3.4.1 as it introduced a lot of theme related changes. So see if there is anything on the WordPress.org page for your theme of on the theme developers website.

Failing that you can …

  1. download again the theme from WordPress.org, in case your zip was corrupt
  2. choose another theme
  3. contact the theme developer via the theme page on WordPress if you really want to use that theme
