Brian,

Thank you for the reply.

Yes, I know that v1.25 is out of date and needs to be upgraded.  I'll
tackle that once I get it migrated over to a new environment.

The original environment *WAS *an XAMPP and was installed as a Bitnami
package.  Because of security vulnerabilities, the entire environment needs
to be upgraded.  But because I used XAMPP, I can't upgrade Apache, or MySQL
or PHP.  I would have to wipe out the entire install and do a fresh
install.  That is not acceptable, so I decided to do what I should have
done the first time, install Apache, MySQL, PHP and Mediawiki as individual
components.

Even though I was successful at accessing the database from the command
line, and verifying the contents, I decided to change the password and
tried the wiki site again.  This time I received an error saying that it
could not find the front page.  This is actually a step forward.  This is
telling me that it connected to the database.

So now I'm facing path issues.  The intitial install was
"/opt/lampp/apps/mediawiki/htdocs".  The new path is "/var/www/html".
After changing the database password, I got the following URL:

"<FQDN>/mediawiki/Main_Page".  I looked in LocalSettings.php and saw that
"$wgArticlePath" was set to "/mediawiki/$1".  I removed "mediawiki" from
the path, stop/started Apache, but now I get "<FQDN>/Main_Page" in the url
bar, and "The requested URL /Main_Page was not found on this server".
Looking a little deeper, I see "$wgScriptPath" set to "/mediawiki".  I know
that isn't correct, so I changed it ".".  I didn't know if that would work
or not.  Apparently not.

There is still a path issue somewhere, but I'm not sure where.  I know that
in the database I saw ""/opt/lampp/apps/mediawiki", but I don't want to
start changing paths in the database until I know that I can at least bring
up the main page.  If there is a path in the database that I need to
change, please let me know where to look.

Thank you.

Daryl
