Good morning everyone,

I have an issue with sandboxes... 3 weeks ago I synchronized the sandbox with the production, it notably added 1 user, modified another one and also modified authorizations and some tables, etc.

It all worked fine for like 2 weeks until monday where I had a problem that corrected itself directly, but now it's back and I don't know what to do.

So the problem is that when I log on using my user account, I arrive on the old Sandbox, the one I had before synchronizing and the URL reads cs1.salesforce.com.
Now, if I log on with the account that wasn't there before the synchronization, I obtain the good SandBox, the address cs2.salesforce.com (that is the same as when my login was working correctly). I tried the logins and all the one that existed in the SandBox before the synchronization obtains the same result as mine...

Please help !
Thank you very much.
