I have two sites on WordPress 5.7.1 and one on 5.6.2. I had installed Captcha Pro on all three and paid for the 5-site license.
I just identified that WordPress 5.7.1 is causing these two sites to lock us out as admins and users. I have deactivated and deleted Captcha Pro from those two sites but I am still getting the error message “ERROR for site owner: Invalid domain for site key”. (By the way, my account on Shamim’s Plugins showed that these two sites were registered and active, and I still had the same message, so it looks like the plugin is not compatible with WordPress 5.7.1.)
The site that is on WordPress 5.6.2 is working fine.
So my problem is that other admins and users need to access the two sites on 5.7.1. Is there some leftover code that didn’t get fully removed from the 5.7.1 sites that is causing us to still be locked out even after the plugin is deactivated and deleted?
Thank you for letting me know. I am still trying to figure out the conflict with WP version 5.7.1
After uninstall this plugin does not have any capability to create any issue. If you get that error message after this plugin uninstalled, That means that error is coming from somewhere else. You can give me the the error page link and i can try to find out where that error is coming from.
