Email section doesn't work after add CP user
Hello! I have add new CP user, try to login to ispconfig 3.1.8p1 and can't see information about emails and users. Ok then, I log out and login with defauld admin (which I don't change anything) And e-mail section does not work. I Click on it, I can see side menu, but then I click to links (Email Mailbox, Domain, etc) nothing happen. If I click on sites all is ok - I see Websites and button "Add new website", but if then I click on Email section I still see Websites section (but side menu changes to email section and clicking on any section menu have no effect)
then I go to dashboard I see all my e-mails in a row with all information. what should I do?
UPD: on Avaible modules I have not Email. I don't know why, it was here but now it does not o_O
