Hello,

Thank you for your patience.

You mentioned that you’re using Rank Math PRO but the account you have used to open this ticket is the Rank Math free version.

Can you please search and forward a receipt from FastSpring.com or the email address you used to purchase so we can locate your account and verify it?

Meanwhile, we might need to take a closer look at the settings of your staging site to investigate.

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:

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.

Hello,

We tried to replicate this issue on the website you shared and even with both the Free and PRO plugins the car remains untouched and any items you add to it remain on it after reloading as you can see on this video: https://i.rankmath.com/v/fU3ALi

If you are still experiencing this issue with the Free plugin, please record a screencast of the issue and share that with us.

Thank you.
