Hi Ferlin,
I am sorry for the late reply.
Regarding your issue, I've patched the fix on your site and now sorting by points no longer hit the sql error.
Anyway i notice almost all your files are outdated. Although in EasySocial control panel it say you are using latest version but when i look at the file, the content of the php files are outdated. I would advise you to re-install EasySocial and make sure all your Joomla folders and readable and writeable
Hope this help and have a nice day
