XF 1.4 Server Errors after users registered


Well-known member
Heya there.

Today we got around 150 New Users (4 hours) and something i notice as i usually follow the users that just registered, is that it started to return me Server Error sometimes i tried to Follow them.

Not sure if this is related with me following people right after they register, but did never happen before.

It's not related to the registration. It's when you followed them and it's a race condition where you attempted to follow them twice. It can be disregarded.

Oh that may be why, i'm noticing today my mouse is double clicking sometimes when i just make 1 click, so that's what caused the server error!
