Site crashed when update today

I have the same problem.
I forced to deactivate the plugin

Same issue, multiple recent threads about this.

same here!

Me too, the ver.1.5.9 has a bug!

Hi guys,
Version 1.5.9 was buggy and removed.
Please check version 1.6 which should be fine.

I’ve updated and switched it back on.

Site is still a bit slower with it on than off but it isn’t causing the server to crash anymore.
