Hello Chuckie3,
Thank you for your question. We are happy to help, but will need more inormation. Are you just trying to login to the Administrative dashboard for joomla?
Do you get any errors? What are the full errors?
If you are trying to get in to the database remotely, here is a guide on Setting up a Remote MySQL connection in cPanel.
If you have any further questions, feel free to post them below.
Thank you,
-John-Paul
