It is possible that the 403 errors you are seeing in the search console are related to the wp-statistics plugin that you deleted a few weeks ago. The plugin may have created URLs that are still being accessed by search engines or users, and since the plugin is no longer active, these URLs are resulting in 403 errors.
To fix this, you can try setting up redirects for the URLs that are causing the errors. This can be done by creating a .htaccess file on your server and adding redirect rules to it. However, if you don’t have access to the host, you may have to contact your web host or website administrator to have them set up the redirects for you.
It is not enough to set the rank. You can try to update your sitemap and submit it to Google search console, also try to create 301 redirects from old pages to new pages, and check robots.txt file if it’s blocking any of your pages.
The link you provided is an example of a URL that may be causing a 403 error. It appears to be related to the wp-statistics plugin and may need to be redirected.
