I’m doing a fresh install on 1and1 and it is working fine until I get to the point where it ask for the database information. When I input the database information it gives me a access denied error.
SQLSTATE  Access denied for user 'dbxxxxxxxxx'@'xx.xxx.xx.xxx' (using password: YES)
Database connection error
I previously installed version 0.7.14800 fine without errors for database.
My last installation I installed on a domain http://www.mydomain.com and this pointed to a folder in my 1and1 shared account that was not the root folder of my account. It worked fine.
Now I am installing the newest version 0.7.15480 on another domain that points to a different folder in my 1and1 account that is also not the root folder of my 1and1 account. This domain is store.myotherdomain.com so it is using a subdomain that is pointing to the folder where I’m installing 7.15480
the domain http://www.myotherdomain.com is actually on a different host and I simply have the subdomain store.myotherdomain.com pointing to my 1and1 account.
I’m thinking my database access denied is related to this issue and not Magento but I thought I’d post it to see if others are experiencing this. I’m contacting 1and1 support as well
