In line 168 of login/index.php we have:
} else if (isset($SESSION->wantsurl) and (strpos($SESSION->wantsurl, $CFG->wwwroot) === 0))

{ $urltogo = $SESSION->wantsurl; /// Because it's an address in this site unset($SESSION->wantsurl); } else { // no wantsurl stored or external - go to homepage $urltogo = $CFG->wwwroot.'/'; unset($SESSION->wantsurl); }

but wantsurl could be also an https link (https://my.site/login/change_password.php or https://my.site/user/editadvanced.php), but in this case homepage is showed. Here my hack:

} else if (isset($SESSION->wantsurl) and ((strpos($SESSION->wantsurl, $CFG->wwwroot) === 0) || (strpos($SESSION->wantsurl, $CFG->httpswwwroot) === 0))) { $urltogo = $SESSION->wantsurl; /// Because it's an address in this site unset($SESSION->wantsurl); }

else

{ // no wantsurl stored or external - go to homepage $urltogo = $CFG->wwwroot.'/'; unset($SESSION->wantsurl); }
