I was sure I was told before by server admins that the server supports SSL. However, I tried to enable that setting and as warned, I was locked out of the admin panel.
Would the adminfix script be able to fix this problem? Can it be fixed at all?
You can simply change the value of field loginhttps in table mdl_config with phpMyAdmin or use command like
UPDATE mdl_config SET value = 0 WHERE name = 'loginhttps'
or try to set to config.php
$CFG->loginhttps = false;
if it lets you to login and change the value from administration menu
