i get * The provided database host, username, and/or password is invalid, and a connection to the database could not be established. Please enter a valid host, username and password" on installation step 2 of 2.I can login with root,admin to mysql at localhost.I created database suitecrm and have access to it from root and admin.Based on the error message above, it is unclear what host, user and password it means. What did I miss in the installation.I cant go to the next step
