Teach me how to program

Read the manual - you are not configuring your access correctly, and using this thread to debug your code instead.
Read the error messages - you do not have the correct username/password combination.

did gsaconst_admin user can access to the database with the hostname "locahost" ? try maybe with 127.0.0.1

try "root" as username without password

http://127.0.0.1/ci3/

---------------------------------------------------------------

I still receive this error message:

Please download the above file in order to get both gsa website file and it's database.

After helping me to fix the file please attached the file back so that I can access the corrected file. 

Thanks in advance.
