Ithemes Better WP Security says Invalid IP returned: ...
I have this problem with the iThemes Security check. I did some debugging and found that this happens when vantage is active.
Now I am on a clean WP
install (5.4.2) and have iThemes Security 7.7.1 activated. No other plugins are there.
I also have a clean Vantage install (4.2.9) activated.
When running the iThemes security check it says: 'Invalid IP returned:' and then a lot of text.
When deactivating Vantage, the error disappears.
What is going on?
