HI Darko, thanks for posting the fix.
I’ll just list exactly what I did on both WP instances.
I installed on the instance where it previously caused the error described and it works now, so that’s a success.
I also upgraded the other instance that was working, but that gave me this error alert: DataTables warning: table id=ip-location-block-statistics-cache – Ajax error. For more information about this error, please see https://datatables.net/tn/7
And I was also not able to update any settings as it kept saying: You do not have sufficient permissions to access this page. This issue was new since I wrote the ticket.
So I uninstalled the plugin on that instance and reinstalled it. This time I did not use the Best for Backend button in both instances and instead I just enabled options manually. I did not enable any ‘Prevent zero day exploit’ options and now both instances seem to be fine.
I saved the emergency login link for both and so hopefully it’ll all be good. I can see ip’s being blocked on the login, which is what I wanted it to do.
Thanks heaps for this!
Rob
