Error connecting to MySQL: 1045 - Access denied for user
This error typically indicates some sort of permissions issue in the database configuration. There are many ways this could happen, but the first things I would check are:
- *That the username/password being used is correct
- *The database user has the correct privileges to access the site's database
Let me know if you're able to make any progress, otherwise, I may have some other troubleshooting steps I can point you towards.
It was my mistake. I just had missed to create the database in advance and then connect it to the CMSB. I wonder whether it would be possible to create the new database through the "One minute installation" page; if it had been possible, it would be easier for the novice user to do a quick and easy CMSB installation.
