That is not related with the previous fix but i found out what is the root issue for this.

The reason why you hit blank page is because you added those new stream on your site, all those stream id stored as 0 instead of id number which caused this issue.

I've help you removed some of the stream data which id equal to 0 from your database, you should able to see your page after login now.

I checked on your site, it seems like most of your Easysocial table missing those auto-increment primary key field which caused this all new stream id become 0.

May i know do you have migrate your site recently?

By the way, I would suggest you that roll back to your previous backup data and see whether those auto-increment primary key field is it still exist or not, because as long as when the user add new stream on your site, it will become blank page.

Hey Aikaterini,

How do we reproduce this error? I tried to login on the front end of your site and did not hit any blank pages. I also tried to logout and it works fine too,
