You need to know 4 necessary parameters for a given MySQL database:
username - selected when adding the MySQL database in Cpanel
password - selected when adding the MySQL database in Cpanel
MySQL database name - selected when adding the MySQL database in Cpanel
and host.
The host depends on whether you connect to the base locally or remotely. If the files and database are on WEBD.pl - you connect locally and the host value should be mysqlhost.
If you have files with another service provider and the database in WEBD.pl and you want to connect it - enter mnXX.webd.pl as the host, where XX is the server number that you will find in your hosting details after logging in to WEBD.pl Client Panel
