wp-admin and wp-login.php not Accessible after Cloudflare

Disabling Cloudflare features on admin pages for content management systems like WordPress

To avoid getting a site offline error message when updating the admin section of your content management system, we recommend setting a Page Rule to exclude the admin section of your CMS from Cloudflare.

Please do the following on the Page Rule interface (we’ll use WordPress admin section as an example):

  1. Go to the Cloudflare Page Rule app.
  2. Input the URL for the admin section, which is in this format: example.com/wp-admin/
  3. Place a * before and after the URL, so it reads as example.com/wp-admin/.
  4. For “Cache Level”, choose “Bypass”
  5. For Performance, choose “Disable Performance”
  6. For security, choose “Disable Security”
  7. Save the rule
