Access denied in MediaWiki database, which even affects SQL queries

Question

I have been working on a separate database for my second MediaWiki wiki (converter.penguinicewikis.com/mw19/) for a wiki family, but there are some problems with it. However, I get error 1142 on that wiki, which says that the SELECT command is denied for the database user to the user table. Also, I tried granting privileges to my second database, and MySQL gave me Error #1044, which said that access was denied for an unknown user to the database of my first wiki. Here is a screenshot of error 1044. Now below is the database error.

Answer 1

Your error message shows that MediaWiki uses the MySQL username "gjlxrtap_mw34555" which don't have privileges on your database gjlxrtap_mw19758.

You run this command

GRANT ALL PRIVILEGES ON gjlxrtap_mw19758 TO gjlxrtap_mw34555 IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

in MYSQL should give the according rights and clear the privvileges cache.
