Wordpress installation does not start after configuring with Ubuntu 20.04

I ran into a lot of inconsistencies between documents so far the best I have found is the document How To Set Up a Remote Database to Optimize Site Performance with MySQL on Ubuntu 18.04 and then continued through with wordpress install but that was to isolate the database on its own server the original how-to-install-wordpress-on-ubuntu-20-04-with-a-lamp-stack I believe had a line that was missing quotes marks. are you at least getting an error can’t communicate with database. or a database error. I would double check your database connectivity through the console and test to see if the name and password your using is accepted through the console. $ mysql -u USER_NAME -p you will be prompted for the password for the mysql username entered in the above line. they should match you wp config file and localhost should be the server name and the database will be what ever you set up when you created the mysql service. I named my database apropar and rmaproparuser that and the password gave me access to the mysql service through the console then type exit and you should be back at the original console prompt. wp-config.php needs to match what you set up your mysql data base with. hope this is helpful to you. I’m still trying to figure out what is wrong with my install but differences are mine already ran the install. but once multisite was completed it started getting Json errors when saving pages and posts and it won’t create a new site or user. the json errors are an easy fix they are due to the new gutenburg editor just revert to the original editor and that probelm goes away. there are three documents that I have found out here that have different requirements listed for the following files: .htaccess; wp-config.php; apropar.conf file the config file in apache after those changes I get nothing. I’ll figure it out . but support here is less then I would like or would offer if roles were reversed. hope this helps
