I managed to can fix that error in AnonySocial
the mistake was in classes/OssnDatabaseException.php

We can't fix this issue, its a non-OSSN issue you have to fix the issue on your mysql configuration.

You have to contact your hosting provider or change the hosting provider.

Hi! Arsalan Shah
still continues with the same error always on News Feed

Reason? This error occurs when the given query limit is reached in MySQL

I do not quite understand this tutorial

You have to change your mysql config see: http://stackoverflow.com/questions/943423/mysql-the-select-would-examine-more-than-max-join-size-rows

The maxjoinsize is 33554432 and can not be changed. Probably the query you're doing joins results larger than that amount.

MySQL setting on the server is fixed.
