Get full access to the database?

Question

PHP

Good day.
Faced such a problem, installed a clean system ubuntu 18.04.1 installed apache, mysql, phpmyadmin
Set up a virtual host. Everything is fine, the site works locally, but when I try to access some post (in particular, a site on wordpress), I get a 404 error, although if I search for this url in the database, I find this post. The permalinks in vp have been updated, so I don’t sin on vp itself, for some reason it seems to me that there is some problem with reading data from the database

Answer 1

Maybe with local rights?
The Apache user should be able to access and execute all the site files.
Look at the error_log Apache writes in sufficient detail about what is wrong)

Answer 2

It seems to me that you have a problem with .htaccess , if there was a problem with the connection to the database, then there would be a white screen in which there was an error reading the data
