Standard plan still getting "Change your plan to restore write access"

[AuthorGEN Technologies Pvt Limited]

Our plan is already Standard still repositories are in read only mode and we are unable to push any code.

Sent many mail to support but no reply.

Need quick help with our account.

What is the first part of the message?  The part that says something like "your push failed because you are over your user limit"?

Ok, log in as an admin and remove one or more user's access.  You have a subscription for up to X users, and you have added another user, so you're on X+1 (or more).

Atlassian systems go read-only when you go over your licence limit.  Once you reduce the users, you'll get full access back, it really is just that you can't write content to them.
