I'm having an issue with my WordPress based site. As it stands, we have an SSL certificate installed server-side that has been validated. On the WordPress side, everything appears to be correctly configured for an HTTPS-enabled site (canonical URL and homepage are entered as HTTPS).
I have tried disabling all of our WordPress plugins to see if there might be an external cause for this problem, but the site still performs a 302 redirect from HTTPS to HTTP even when all plugins are disabled. Strangely, HTTPS is enabled in the WordPress admin directory of our site and all of those requests work perfectly without redirection.
Note: We are using PHP 5.3 and a slightly older version of WordPress 5.3.24, but I'm not sure if migrating to newer PHP and WP versions will fix the problem.
Any help is appreciated!
