I’ve noticed that the Membership2 plugin is unstable at times.
The main thing I noticed is that it will conflict with another 3rd party plugin called ‘Better Search Replace’.
When MembershipPro2 plugin is on, I have to select each table (ctrl + click) one by one (inside Better Search Replace) whereas with it disabled, I can shift click all tables at once.
The other issue is that when I try to deactivate MembershipPro2, it will look as if it has been deactivated but then it still offers the button to Deactivate. This is a weird behaviour.
