To install a phpBB template you should have a phpBB2 board system installed on your server.
Download it from
www.phpbb.com if you don't have
one. The installation process is quite simple. Decompress the phpBB2 archive to a local directory
on your system and navigate to the
"/docs/" folder the
"readme.html" and the
"install.html" files, these files will walk you through the
basics on installing the forum software.
When you have a phpBB2 board system installed, unpack the template package. There will be a
folder named
"Forum_XXXX" (where XXXX - is a four digit number). This is
a phpBB2 theme. Place the files in their own directory ("Forum_XXXX") in the
"templates" directory inside your phpBB2 directory.
If your server is online somewhere, then you'll first need to unpack to a directory, and then
upload it to your server. Do not rename
"Forum_XXXX" directory.
Go to your administration control panel.
Under
"Styles Admin", click on the link
"Add" you will find a list of styles that are present in
the
"templates" directory but that haven't been installed to
your forum. Behind every style, you see an
"Install" link. Click on that link to install the
style.
If you've done this for all the styles that you wanted to install, then have fun! They're now
available to your users, or to you to set as the default style in
"General Admin > Configuration".
