Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.
Please check your browser console for script errors when you save your posts.
If you see an error containing “updateMeta”, then your server must be blocking Rank Math’s API. Please refer to this guide to fix it: https://rankmath.com/kb/meta-data-not-saving/#firewall
Let us know how that goes. Looking forward to helping you.
Good morning,
I checked the console and there are several errors displayed but I have not seen “updateMeta”.
Failed to load resource: the server responded with a status of 404 ()

Thank you:-)
Hello,
Can you please reinstall the Rank Math plugin and see if the issue is resolved?
You won’t lose any existing settings as the settings are saved in the database.
If the issue persists, please take a backup of your .htaccess file and replace it with the default WordPress .htaccess file. You can get the file here: https://wordpress.org/support/article/htaccess/
You can follow this guide to edit the .htaccess file:
https://rankmath.com/kb/edit-htaccess/
Let us know if the issue persists.
We are here to assist you.
Hello:-)
I followed all your instructions.
Unfortunately, the problem persists.
I hope you still have some ideas on how to solve the problem…
Have a good day

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.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
I logged into your website’s admin area and was able to replicate the issue.
Upon investigating with the Health Check & Troubleshooting plugin, I enabled only Rank Math with Oxygen Builder and the issue was fixed. Please have a look at the complete screencast in the sensitive data section of this ticket.
It seems like some other plugin/theme is conflicting and causing the issue. Please follow this guide to determine the plugin/theme causing the issue here: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
Let us know how that goes.
Thank you.
Good morning,
Thanks for your help:-)
I did some tests by reproducing what you did in the screencast.
The problem is that there are a lot of plugins that I have to disable in order for this to be no longer a problem.
However, as soon as I deactivate Rank Math, the problem no longer exists…
Without I need all my plugins:'(
I don’t know what to do about it anymore.
Have a great day:-)
