I have 1 Odoo account and I can log in to it.

I have the ecomerce module and an Odoo website.

The website is published, I can see it on the internet.

When I log in to my Odoo account, There is no possibility (no link) to go to my website as user (so that I can edit it and build further).

My Odoo account says that I have no database yet, and proposes me to create one.

But I have already one, my website has some pages and content.

I always stayed logged in on my website, but today for no specific reason, I logged out and tried to log in again, via my account. 

Because I have no login button on my website (I removed it since I am the only user / admin, it is not relevant to visitors of my site.)

What is possibly going wrong?
