many things messed up after last update

I literally had to take my website offline for a day. I tried to re-configure it all to the new update but somethings still didn’t work. The support forums are full of unresolved issues. I wasted hours trying but I have a membership website with around 200 paying members, having this plugin break is not good. I can’t afford to have this happen again in the future. I moved to a different plugin.
