Hello,
We apologize for the inconvenience you’re experiencing with saving the meta titles and descriptions on your WooCommerce pages. Thank you for providing detailed information about the steps you’ve already taken to troubleshoot the issue.
Based on the information you’ve provided, it seems that you’ve already ruled out plugin conflicts, theme conflicts, and JavaScript-related errors. Since your host has confirmed that they are not blocking requests to the Rank Math files, we can explore other potential causes.
One possible cause could be a firewall or security plugin blocking access to the Rank Math REST route. To check this, you can visit the following REST route in your browser:

If you encounter a notice that your access has been denied by a firewall, it’s likely that your site’s firewall is causing the issue. You can refer to our guide on unblocking Rank Math from your firewall for solutions.
Additionally, if you’re using Wordfence, it’s important to ensure that Rank Math’s files are whitelisted in Wordfence to prevent any access blocks.
If you’re using Cloudflare, adding page rules in Cloudflare to disable security for the Rank Math URLs might also help resolve the issue.
Please let us know if these steps help resolve the issue. If not, feel free to reply to this ticket, and a human agent from our support team will assist you further.
Thank you for reaching out to us, and we appreciate your patience as we work to resolve this issue for you.
Best regards.
