I am struggling with my Moodle instance as follows:
I installed Moodle (3.6.3) on a hosted server (Siteground) which worked beautifully. I then used the provided cPanel interface to install a 'Let's Encrypt' HTTPS certificate with "HTTP enforce" and "External Links Rewrite" enabled.
Since then, I cannot login to my site. I input my username and password, and just get redirected to the login page. No exceptions or errors are thrown.
I have no idea why this might be happening, or if I have installed the cert incorrectly. I did run the HTTPS Conversion Tool from Server Settings prior to installing the certificate on my server.
Am I missing something? Please also let me know if I need to provide more information regarding my installation.
