I've had Wordfence installed on my site for sometime and it's always worked great. As of today it won't progress past 'Preparing a new scan', but it doesn't do anything else. It works fine on another site I'm using Wordfence with so I'm not sure what the problem is.
I'm using Cloudflare on the site that's having issues with Wordfence. When I run the 'Click to test connectivity to the Wordfence API servers' I get a 524 error from Cloudflare.
