I have installed Cyberpanel on my server and it is running on Ubuntu 20.04 LTS. Everything is going on fine until at the point where I have to install WordPress using the installer. At that point the installation fails with the message "Installation failed. Error message: ." I have done this several times over and I have this error.
When I look into the installation directories, all the files for wordpress are there. When I load the domain url on the browser, the site is reporting this error: "Error establishing a database connection."
