This come up once before here:
And I can confirm I’ve experienced it while testing and troubleshooting on a Free and Pro plan.
Currently, there are some “Cloudflare Free Managed Ruleset”, which are working good, however some users who try to edit wp-config.php
via WordPress or cPanel File Manager get the “blocked page screen”.
From one perspective, it’s a good thing, from the other, it’s causing those unexpected behaviour which then results in confussion for the Cloudflare users.
Furthermore, as on a Free plan, currently we cannot “Add an exception” for that or some other particular “Managed Rule” because there is no button for it, yet, as it exists for a Pro plan which contains it.
I also tested and got the error bar at the bottom that the ruleset cannot be found (Free plan).
If your case is the same as I described above, I’d suggest you to edit your wp-config.php
file by manually downloading it via FTP, modifying it, then re-uploading it.
It’s also a safer and much better way than allowing some plugin, or a hacker exploiting the WP plugin finding it’s vulnerability to edit your Website’s wp-config.php file.
So, my best guess is either Cloudflare has to modify something in the CF dashboard to allow us to “add an exception” even for them on a Free plan. Otherwise, the error we’re getting could be a temporary untl then as far as disabling/bypassing via Firewall Rules and via Page Rule doesn’t help at all.
I’ll do it for us and write back as soon as I get some more feedback information about this.
