Thanks for your willingness to help, but I was able to finally figure out why the:
Error establishing a database connection
…error was occurring. This error was a result of how the basic Database Name, Database Username and Database User Password are set up, by each of the various utilities.
When creating a website with ee, the input is quite easy. I choose the Database Name, Database Username and Database User Password ahead of time, note them in a secure space, and then copy/paste them into the ee interface. It works without a hitch.
However, the ee interface handles the characters in these names differently than the MySQL command line, phpMyAdmin and other Database utilities handle them. Some characters are not treated equally when using the same copy/paste method to change the Database Name, Database Username and Database User Password.
I’m not going to go into a lot of detail about this, to protect the naming convention and scheme I use, it should suffice to strongly suggest even when viewing the Database Name, Database Username and Database User Password in the wp-admin.php and matching them up in the MySQL command line or phpMyAdmin, even if they appear to be the same, THEY MAY NOT BE!
I was able to change the Database Name, Database Username and Database User Password and this error went away. I was also able to delete the website and use ee to create the website again, using the same convention and scheme I used before and the error never showed back up.
FYI: this issue was NOT an instance of a typo or fat fingers
