Thread:Project:Support desk/Cannot contact the database server: Access denied for user/reply (3)

Overwriting an old wiki version with the files from a newer tarball does not touch LocalSettings.php. If it worked before and does not work now, then you must have changed something with LocalSettings.php. What did you do? Have you recreated the file?

Anyway, what you can do is to put the following lines at the very bottom of your LocalSettings.php file:

echo $wgDBserver. "\n"; echo $wgDBname. "\n"; echo $wgDBuser. "\n"; echo $wgDBpassword. "\n"; die("END");

This will put out the according information onto the wiki page (do not forget to remove them again afterwards!). Is this information - all four of them - correct?
