Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Could you please get in touch with your web host and ensure that the ModSecurity is disabled?
Disabling ModSecurity should fix the issue.
Looking forward to helping you.
Hi!
Thank you for coming back to me.
I use WPengine, and they tell me:
“So modsecurity is a security module that’s enabled on our platform – unfortunately it’s not something we’d be able to deactivate from our end though – Terribly sorry for any inconvenience there!”
Any other ideas?
Hello,
We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):
https://wordpress.org/plugins/wp-security-audit-log/
We really look forward to helping you.
Thank you.
