If you changed the password within the last 24 hours, it might not have updated on all of the Services yet. If it does not work in the next 24 hours, please try changing it via the Client Area. Please use the Client Area to better ensure that the password is changed everywhere.
I have checked your account and I can tell that you haven’t followed the instructions from the article.
Please reset your hosting account password through the client area, then login to the control panel and then open phpMyAdmin.
I can see the client area password is out of sync, which means you used the password reset functionality in the control panel. The control panel password reset functionality is broken and you should never use it. You can always view and change your account password through the client area.
I wish I could disable that function entirely, but I can’t, so the best I can do is provide tools and instructions to work around. So that’s what I did, and the tools and instructions work. Please use and follow them, because they will work for you too.
