title: WordPress theme-options page loads blank
body: <p>I am making a redesign of my clients website through the CMS wordpress.
  They want to keep the same theme, so I would need to make some changes to the basic theme options etc.</p>
  
  <p>Every time I try to open the theme_options page it loads a blank page. A completely white screen, and by inspecting I can see that there is NO html what-so-ever loaded. not even the wordpress frame.</p>
  
  <p>After this accident happened, I have tried to update all their plug-ins without any luck, and I have tried to deactivate the plug-ins without any luck.</p>
