How to add a database user to config.php

Question

I am a self taught web developer so excuse my lack of skill when it comes to the more complicated issues. I am running joomla 3.6.5 and PHP 4.0.10.18 I recently changed domains and can no longer access the administrator of Joomla. I get this error when I try to log in. "Not Found The requested URL /administrator/index.php was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

I believe I have it narrowed down to a problem with the congig.php file. The user and password that I normally use to log in is not in the config.php file.

If someone could point me in the right direction I would be very grateful. Also if I can post anything more to help let me know. I'm not sure if it's safe to post my config.php file. Many thanks!

The user and password you use to login are stored (securely) in the database.

The configuration.php contains the host, database name, login and password relative to the database access.

Your error means something different though: it could be that you have moved your web root, you placed an .htaccess that routes the admin wrongly (possibly in an attempt to protect it from unauthorised access), so first of all ensure your web root is there where it should be:

For example, add a comment line to your robots.txt (such as

#comment

at the very end), then load it through your browser: http://example.com/robots.txt

Can you see the line?

• No : You think your webroot is where your robots.txt is, but it's not.
• Yes : Is the administrator folder there?
  • No : Extract the Joomla Upgrade package over this folder and possibly it could start working.
  • Yes : Rename the .htaccess file to something else, possibly it's its fault
