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
- WordPress Configuration: Adjust site and home URL settings to use http:// instead of https://
- Control Panel Settings: Disable the Force HTTPS option in your hosting control panel
- Plugin Management: Deactivate the Really Simple SSL plugin
- 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.
