2 Issues could be 1 problem - no PHPmyadmin access and Localhost8080 (1 reply)

I need help desperately please! I was able to get in to PHPmyadmin and get into my WP site via localhost80. Long story short, unless we need a phonecall, lol, I changed from 80 to 8080 then back to 80 (as for some reason it was giving me error messages about port 80) and now when I want to log into PHPmyadmin, it says ://localhost:8080/phpmyadmin/ and obviously the page can't be reached. I manually change the URL to 80, and when I try to log in with root, password is empty, I get at the top of the login panel

Cannot log in to the MySQL server

and then

mysqli_real_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using password: NO)

I'm afraid that all the work I'm doing on the WP site won't be saved in the PHPmyadmin. Can someone please help me?

Many thanks
