 * Hello,
 * Any time a particular user tries to duplicate a post, they receive the following:
   
   Error duplicating post: Unexpected token ‘<‘,”<!DOCTYPE” .. is not valid JSON
 * It only happens with this single user. I can duplicate the same post with no 
   error. I’ve tried various browsers with them, numerous different non-connected
   posts, browser cache/dump etc. I am on the latest version of everything. Any 
   help would be immensely helpful, thank you!
