Installation failed: Destination folder already exists.

Hello,

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

I am sorry but we don’t reply directly to your inbox at the moment. All replies will be posted here.

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,

This error appears when there is already a folder named SEO by Rank Math in /wp-content/plugins/ directory of your site. Please remove the folder from there and then try to install it again.

If you want us to check then please provide FTP access to your site.

Looking forward to helping you.
