Website Login URL doesn't show correct UI

[egzibeo]

Hi everyone,

I created an ecommerce website a few years ago , worked on it, had it up and running. Until one day that I had to put it in maintenance mode because due to circumstances I couldn't take care of it. A year or so later, now, I am coming back, trying to revive it. The problem is...the login URL for my website shows the same UI as the simple address to my website. In other words, the login interface doesn't make a difference. The hosting provider says it's a prestashop issue. Do any of you think is a prestashop issue or a hosting issue? I would need to know so that I don't pay another year of hosting, if the issue is from their end.

The problem is, or I think it is, if I can't login into my website (the URL for logging in doesn't show the UI to allow me to login, meaning a field for username and one for password, how can I update prestashop? 

Help :) Thank you.
