Why do I get an ERR_SSL_UNRECOGNIZED_NAME_ALERT error?

Main Issue

When accessing temporary URLs (like example-co-uk.staging.com), users encounter an SSL error because the temporary URL can't load over SSL (via https://).

Solution Steps

  1. WordPress Configuration: Adjust site and home URL settings to use http:// instead of https://
  2. Control Panel Settings: Disable the Force HTTPS option in your hosting control panel
  3. Plugin Management: Deactivate the Really Simple SSL plugin
  4. File Cleanup: Remove any redirect rules from the .htaccess file that might force HTTPS

Additional Note: After making corrections, try an incognito browser tab to ensure HTTPS settings aren't cached locally.
