save it as .htaccess and upload to the same place mainfile.php is located.

Or add the following line to mainfile.php right after the file credits:

Download the latest
version from http://phpnuke.org
, unzip or untar it to a local folder on your computer.

To unzip or untar means to open the compressed file so that you can access all
of the included files, when you download any program it will often come compressed
into one file, it will either be a exe, zip or tar.gz, exe's run by double clicking
them, zips and tars require a program to uncompress them, the most commonly
used programs to handle this task are Winzip and Winrar, install one of them
or install both, once you have any or both installed you can simply right click
the tar file and select extract to some/folder/name/here, the tar or
zip will extract to the selected location.



Now that we have uncompressed the files we can prepare them before finally uploading
them to the server, there is only one file that needs to be edited and that
is config.php, the zip or tar you just uncompressed will create a folder on
your hard disk, it will most likely be named PHP-Nuke-7.3 (if you were using
Nuke 7.3), inside of that folder you will find 3 folder: html (where all of
Nuke's files are stored), sql (which includes the file needed to create Nuke's
database tables) and upgrades (which includes scripts used for upgrading Nuke
from a previous version), config.php will be located inside of the html folder.

Common error note: Search the net for a suitable text editor like Context,
editpad or similar, Do Not Use Frontpage, Dreamweaver, Notepad, Wordpad or
similar programs to edit php files WYSIWYG (what you see is what you get)
programs like Frontpage and text editors like Notepad often add html tags or
blank spaces to php files which cause them to malfunction, problems caused by
these programs are tricky to troubleshoot so please avoid using them.



We will now edit config.php, the settings in it will allow Nuke to connect to
the database so that it can retrieve and/or store data into the tables, if you
haven't bought web space from a hosting company get it now, check with them
if they support php, mysql and if they have GD libraries installed (these are
required for the security image in Nuke's login and registration pages), when
you get web hosting they should email you all the details of your new account,
among these you will find the username and password for the mysql database and
the name of the database, these are required for the settings in config.php
so if you did not get them from your hosting provider contact them and ask for
these.

Open PHP-Nuke-xx/html/config.php on a text editor, go to line 32 and
edit the following so that it matches your MySQL database login info:


$dbhost = "localhost"; (most likely this can be left as is)

$dbuname = "database_login_username"; (the username given to you by the hosting
provider for mysql)

$dbpass = "database_login_pass"; (the password given to you by the hosting
provider)

$dbname = "database_name"; (the name of the database given to you by the
hosting provider)

$prefix = "nuke"; (if this is your only Nuke site leave as is)

$user_prefix = "nuke"; (if this is your only Nuke site leave as is)

$dbtype = "MySQL"; (most likely this can be left as is)

You can leave the rest as is for now. Upload all files contained inside of the
html folder into the server via ftp. Suggested FTP programs are WS_FTP,
Filezilla and Smart FTP, if you have experience with ftp use any program you
feel comfortable with, if this is your first time using ftp use WS_FTP, HERE
is a simple illustrated tutorial on FTP usage and chmod.

Load the database tables found in sql/nuke.sql, the normal way is to
use
phpMyAdmin, or you can use
nukesql.php to load them without using phpMyAdmin.

Now depending on the version of PHP-Nuke you are using you will need to access
the admin section:

For pre-5.5 versions, point your browser to http://your.web.site.com/admin.php,
the window that appears will request for a login name and pass, use God
as name and Password as password, you will now be able to edit your admin
preferences, the first of which should be to click on Edit Admins, change
the name and pass of the God account so no one else will be able to access it.
Then you might want to click on Preferences to customize settings for
your website..

For 5.5 and newer versions point your browser to http://your.web.site.com/index.php
in that page you will find a introductory message which will have a link to
create admin account, click on it and in the new window enter your desired
username and password, Select a username and password you can remember with
ease but make them hard for others to guess, your password should be around
8 or 10 characters long, you will be asked if you want to create a normal user
with the same nick and pass, select yes. Once this has been done you can login
as an admin by pointing your browser to http://your.web.site.com/ and
as a normal user by pointing your browser to http://your.web.site.com/account.html,
at this point you will be able to edit your preferences.

• Does your theme folder contain the theme files that you need? In other words, if DeepBlue is your theme, then you should have themes/DeepBlue/theme.php as well as other files.


• If the above is not the issue, then, using phpMyAdmin, make sure that you have a table in your database called nuke_config. Yours may be something other than nuke_ depending on your $prefix setting.


• If the above 2 things are not the problem, then you are probably not connecting with the database at all. Meaning, either the database does not exist or your database settings in your nuke config.php file are incorrect. Verify the settings for $dbhost, $dbname, $dbuname, and $dbpass are correct with the database setup.
