Hello! I finally bought the dislike add-on but for some reason it is not installing for me. I uploaded all the content via FTP then uploaded the xml file via the admin panel but it is not installing. The problem is after i upload the xml file after 2 minutes i get the: http 500 error and blank page. Problem with my server? I even closed my board to install the add-on but same problem. I tried to install other add-ons and they work. It is just this add-on that won't install what could be the problem?
