Instalation - SQLSTATE  Access denied for user - what to do ?1 user found helpful
Pretty simple problem (I think) I'm trying to install concrete5 on my FTP and MYSQL. I'm new to MYSQL and databases. I run my website from ftp and index.html at the moment.
So I type in my password, server and all. I get the error above + some details.
Can some1 suggest what to do ? My MYSQL /FTP is on sql.username.nazwa.pl
The solution was removing certain characters from the password.
depending on this you could try several options:
localhost:3306 (or 3307, 3308, 3309, 3310 depending on your dbase version mysql5.1 has 3309)
Remember you need to run PHP 5.3.3+ to run concrete5. If none of the above help, try setting your PHP to 5.4 and retry. Also, just in case, make sure you can connect to your database with the U/P you're entering when installing C5.
best of luck
