When I scan for domains using Softaculous Wordpress Manager, all sites on my host come up properly as https:// except my main domain which comes up as http:// and 'database connection failed'. https:// is correctly input in the WP general settings, and the wp-config file database info shows correctly in the Softaculous 'edit site details' page, but when I use that detail page to edit what shows as http:// to https://, I get the error message about the database.
Any idea how I can get my https:// domain properly read/scanned by Softaculous without it defaulting to http://?
