Hey there,
Did you update your EasySocial with the single click updater? If yes, it is a known issue. It is recommended to download and install launcher or full package installer found on your dashboard and run the installation as usual. The single click updater should be up and working by v3.0.4.

If no, may I know how did you update your EasySocial?
Can we have the permission to update the EasySocial for you? If can, please perform a full backup of your site before we upgrade it for you.
