Scan Not Working With Cloudflare

Can you temporarily enable “Enable debugging mode” (on the Wordfence Options page, fairly near the bottom) and try a scan again, then post about the last 10 lines of what you see in the yellow “Scan detailed activity” box?

If nothing is in the box, there may be a javascript problem preventing the scan from even being requested properly. Usually you can see errors like this in the javascript console — if you haven’t used the javascript console before, here are some instructions:

(Make sure to turn this back off after resolving the issue — it does slow down scans and take up more space in your database.)

There are also a few troubleshooting steps you can try, but I don’t think any are related to CloudFlare — but it may be possible that other differences between your sites/plugins/etc. are causing the trouble:

If you have added any code in your .htaccess file to block wp-admin, you might need to disable that, or at least allow requests to admin-ajax.php through.

When getting stuck at that point, some people have had success turning on “Disable config caching” on the Wordfence Options page, but I’m not sure if that will help in your case.

Usually you can also disable “Start all scans remotely”, unless you needed to turn that on for another reason.

You might want to check on the other items in the “My scans aren’t starting” link above, too — and if you know where to find your site’s error log, there may be an error message that will help there.

I figured out the issue. It was something stupid on my part. Thanks for the help though!

I have the same problem. So thekendog, I am interested in what stupid thing you did.
