An MEC update has locked out all MEC Pro features, such as bookings and taking payments. There is already a thread in the general support forum, but I thought it worth posting here in beta, hoping the dev team can jump on it, as sites with Bookings enabled are currently unable to transact.
This lockout was first noticed around 5 hours ago on our sites using MEC bookings.
Just to say I am not seeing the same problem (Yet)
as an idea, have you tried removing the plugin and reinstalling via Pro Validation, it can sometimes solve these kinds of problems
Thanks @scotbaston - tried that, but still have the block on all MEC Pro modules. I am on MEC version 7.36.3. Hopefully @charlie and the team will get it resolved quickly! 
I’m on 7.35.1 here (multiple sites), when I tried to update to 7.36.3 it wasn’t available (last week I logged a call to make it available)
This particular site is on auto-updates (client wishes), so it self-installed. I would avoid 7.36.3 until Charlie has a fix!
