Hi @autumn00,
In some cases, Wordfence may block the action of a plugin that updates META content. However, I took a look at your other topic, and in your case, the code was manually added to the header.php file. I checked the HTML for the domain you linked and I do see the META tag in place. This is not being blocked by Wordfence.
Instead, it is possible that when AdMaven tries to verify, their bot may be blocked. You can check this by keeping an eye on the Live Traffic log in Tools > Live Traffic while trying to verify. If any new blocks appear there, you can click on the block listing to view details on why the block occurred. Please feel free to share a screenshot of the block here so we can take a closer look.
If you don’t see any new blocks listed in the Live Traffic log when you attempt to verify the META tag, I recommend reaching out to AdMaven’s support to see what kind of response they’re getting when trying to verify.
Thanks,
Margaret
