Buddypress and Paid Memberships Pro emails stopped working

Hello

I’m always trying to improve my site and last night I installed the Paid Memberships Pro Register Helper plugin and another plugin to monitor my plugins’ memory usage as site can be slow. Today I realized my new members as well as myself are not receiving the typical registration emails that come from BP and PMPro. I have uninstalled both new plugins and even deleted them but the problem is still there. I created a couple of test memberships and have not received any notifications. Any ideas what else might be the issue? Something is affecting all the site emails. I did test it with my personal adress as admin address and still nothing.

I provided the login details in case you want to take a look around at my site.

P.S. I have installed few other plugins in the last week as I was getting fatal memory error but they didn’t seem to cause a problem until last night. This includes Heartbeat and Fast Velocity for minifying. Fast Velocity cannot be turned off as the site will get fatal error.

This is a big issue as I verify all my members and assign their membership + they need to confirm email and they are not getting any of this. I now have to email them personally to say they are approved.
