Connection failed: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost'

[srissman]

I ran into the same problem "Connection failed: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost'" and finally discovered the solution:

My password contained a special character.. specifically a '$'. Once I updated the password in mysql, then updated it in ispcp with '/var/www/ispcp/engine/ispcp-db-passwd' I was able to complete the install.

I hope this helps others... now to test to see if the updated succeeded for true!

Congratulations!
