Database error on one computer, but not another

[Shila]

I just moved my shop from one server to another. At first I got the database info wrong and got the following message:

 

Fatal error: Uncaught Link to database cannot be established: SQLSTATE[42000] [1044] Access denied for user 'xxx'@'xxx' to database 'xxx_xxx' thrown in /home/xxx/public_html/classes/db/DbPDO.php on line 57

 

I changed the info and somehow got everything to work, so I thought.

 

Cause, when someone from another computer try to acces the shop, they get the database error. But if you acces the shop like domainname.dk/somethingwrong it goes to the 404 page and after that, everything is working fine.

 

What to do?
