Installed Docebo 3.6.0.4, ran the db_full.sql script to create/populate the database.  I made all of the changes to config.php, and I am able to connect to the application and come to the login screen.  I checked the table, core_user, and found the one user id, with a blank password.  When I enter that username without a password into the login screen, I receive the "Access denied, maybe you have inserted the wrong password" message.  I tried to changed the username, added a password through PhpMyAdmin (wasn't sure if the PWD field would be encrypted), and that did not fix the problem.  Stuck and can't find anything in the documentation to assist with this issue.

why you run the .sql file?
The installer creates all alone, you don't need to upload database by yourself.

hello,
as suggested by claudio you followed a wrong installation path: if the installer finished without errors you didn't had to manually run any sql file and allowing the config.php to be writeable by everyone (just during install) you don't need to then edit it by hand.

you can now try to change the password for the default user in database, for example using phpmyadmin just edit the line, fill in a password and before saving select MD5 in the function dropdown on the same line of the password field.

bye,
Giovanni.
