After the reconstruction od the page, I've been having several problems with my students:
* Some students can not enter the page: BAD REQUEST sign
* The score of the students are incorrect
* Some students can not login - they know the username and login, but they can't access
* Some students forgot their passwords and we don't have access anymore
* We, as teacher, don't have access to the correct answers (how was it made?)
Can anybody help me, please?
I and my students used to love using this website, but now it's impossible to use it.
