Fresh installation and strange behaviors

Hello, I have made a fresh installation of Opigno with Composer on Debian 8 and I have obtained the following strange behaviors: 1) As I read in another thread, the messages are not deleted when they are marked as read, in fact it does not change the state when marking as read. 2) In basic configurations of the site, the base address http://lms.example.com/web is determined, however, if we type http://lms.example.com in a browser it does not redirect to the base page and the error 403 Forbidden appears. This error also affects the training subscription link that is sent to the user. However, it does not affect the user registration link. In the first case, a link of the type is received: http://lms.example.com/web/user/reset/21/1551519375/QqA9LYViwcLBJ08CcAZ… While in the second case a link of the type is received: http://lms.example.com/group/2 Are they really strange behavior of the platform or is it due to some misconfiguration on my part? Thank you for your attention.
