I tried submit issue from https://support.gitlab.com/hc/en-us but it doesn’t work.

I can’t confirm my email. The first one, i tried registered account on GitLab and didn’t recieve confirm message. Later i tried again, and i get error (after confirm)
"1 error prohibited this user from being saved:

When i try login i get error “You have to confirm your email address before continuing.”
Please help me register on GitLab.
