Which version do you have installed?
Do you see any errors or notifications?
2.0.1
No, nothing. no errors. I press “save changes” and everything appears ok, but if I reload the page or exit the settings and enter again, all the changes made in username blacklist return to their origin. 🙁
It is curious that in “Blacklisted emails” it allowed me to enter new TLDs without any problem and they are correctly saved. The problem is only in “Blacklisted usernames”.
Works for me on version 2.0.1.
Make sure you’re not loosing the newly added terms as the array gets sorted when saving.
An easy test is to ban the username ‘aaaaaa’ which should appear right at the top, making it easy to spot.
I have tried everything. I have deactivated all plugins, uninstalled your plugin and reinstalled, updated everything… and everything is still the same. Anything I add in “usernames blacklisted” on reload disappears and anything I delete, on reload is there again. 🙁
So adding something like aaaaa doesn’t get added? Weird.
Please check your servers error_log file for errors.
The error_log file can usually be found in your hosting dashboard. Anything mentioning AdRotate is interesting.
