Thank you tim for your reply, but unfortunately nothing has changed. all are the same like before
I have used the admin/replace.php script to change the db entries from http to https, but it runs in just a few seconds and not described in a few minutes without any error.
On the config.php is change to https://....
I have deleted the browser cache and restarted the hole server.
I have tryed with the setting to logon with a secured site and without one....
Its every time the same.
Why can moodle not use relative links in all the documents, like a normal web site?
Any other idea tim?
