 * I am getting the same error after migrating my live site to local (so regenaration
   would go faster).
 * Permissions are set to allow everything, paths (file and url) have been updated
   in the database. What gives?
 * version 0.6.3

 * A possible issue might be, that the server is throwing 403 error pages if it 
   is set to temporarily block ip’s which accessed the server n times/second. Since
   the script runs through ajax, I’m getting _undefined_ errors…
