Hi @jfortune, sorry to see you might be getting blocked by your own site.
“A potentially unsafe operation has been detected.” suggests that you need to enable Learning Mode to prevent false-positives when loading certain pages or performing certain functions like updating posts, uploading files, etc. You can read more about this (and also a method of allowlisting from the feedback you see about the block on the Live Traffic page) here: https://www.wordfence.com/help/firewall/learning-mode/
When you’ve been accidentally blocked, rename the /wp-content/plugins/wordfence plugin folder to “wordfence_bak” (without quotes). This should let you access and log into your site normally.
You can then rename the folder back to “wordfence”, but if you become blocked again immediately it’s sometimes necessary to install the Wordfence Assistant plugin to disable the firewall before trying to reenable Wordfence. This would allow you to remove your IP block from the Wordfence > Blocking page.
Don’t forget to also reenable the firewall again, although if IP detection is incorrect on your site then a legitimate block for another visitor/bot may block everybody including yourself and be the reason why you were originally seeing the page. To check this, take note of your own IP on your main device: https://www.whatsmyip.org and head over to Wordfence > All Options > General Wordfence Options > How does Wordfence get IPs. Reference the area under that section that says Detected IPs and Your IP with this setting. See if any of the options there when picked accurately reflect your IP. If one does, don’t forget to hit the SAVE CHANGES button in the top-right after you’re done.
Thanks,
Peter.
