- Plesk Onyx for Linux
When opening a WordPress-based website in Site Preview, the page gets redirected from http://203.0.113.2/plesk-site-preview/example.com/203.0.113.2/ to https://example.com.
The .htaccess file does not contain any redirection rules.
The Permanent SEO-safe 301 redirect from HTTP to HTTPS option is disabled in Plesk at Domains > example.com > Hosting Settings.
Redirection is performed inside WordPress.
Disable redirection in WordPress. Check WordPress plugins like "Redirection" in the WordPress instance of the affected domain.
