# Theme Activation = Server 500 Error

 * I’m having a strange issue a one particular theme purchased from ThemeForest.
   Several other folk seem to have used the theme successfully, and no-one else 
   has commented at TF with any such problems. But the second I “activate” the theme
   in WP Admin, it breaks the front & backend of the specific blog with Server 500
   errors.
    - I am running WordPress MultiSite 3.1.3
    - I have tested this on both a live server and my local server (MAMP-powered
      MultiSite 3.1.3 with domain mapping, which I love more-than lime cordial) 
      and theme activation breaks both instantly
    - I have tested this theme on different blogs on local MultiSite Network and
      theme activation breaks each blog instantly.
    - The second I revert to any other theme (which I have to do via *Network* Admin
      because the individual blog’s WP Admin is 500’d), the server errors vanishes
    - So I sent this theme to a friend of mine so he could test it on his local 
      MultiSite install and everything worked perfectly for him; no breaks what-
      so-ever
 * Could it be something to do with file permissions?
 * So I’m pretty confused. Any help will be rewarded with green cordial vouchers.

 * I found the conflict, but not the problem. It’s one of the plugins in my mu-plugins
   folder. This is the only theme amongst the 50 in my MultiSite install that has
   this problem, so not yet what the cause is.
