Hi kingandsona;

It looks like you just have the wrong user/host/password combination for PHPbb to log into the database. So you’ll either need to change the password in your PHPbb setup to match what is in the database, or change the password in the database itself to match what you have in PHPbb. If you do not have access to the database at all, you might have to reset the root user password so that you can gain access to it.

Once you gain access to the database, you can change your PHPbb user password using a command similar to the below:

SET PASSWORD FOR ‘lalunxxxxxx’@‘91.2xx.1xx.2xx’ = PASSWORD(‘MyNewPass’);

You’ll have to replace the above with your actual user / host since it’s masked, and whatever password you want.
