Rank Math free

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Please make sure that both the Free (1.0.63) and PRO (2.7.0) plugin are updated before trying to activate the PRO version. https://rankmath.com/changelog/

In case you are running older versions, please update both plugins to the latest stable release.

If that does not work, it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:
https://rankmath.com/kb/check-plugin-conflicts/

Only the site admin would know and your users won’t be affected by this troubleshooting.

We really look forward to helping you.

Thank you.

Hello,

I do not use the Pro Version. I only have the Free version installed. I de-activated all of the other plugins, but still cannot activate Rank Math.

Any other ideas?

Thank you,

John.

Hello,

Thank you for the update.

Could you please confirm if you have tried reinstalling Rank Math? Please also check your website for Rank Math’s requirements at this link:

If the issue still persists, we might need to take a closer look at your website. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

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:

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):

We really look forward to helping you.

Thank you.
