if none of the themes work. you are not installing them correctly.

to install theme

extract all contents from package FIRST beofre uploading!


In the package is a folder called themes. In that folder there is the THEME folder.
we will call it DarkBlue.

Upload the Darkblue folder to your /themes folder on your FTP where your nuke site is. Leave the contents AS-IS..do not change anything in that DarkBlue folder. Just upload it to your themes folder.
THAT IS ALL.
Do not separate the forum template from the nuke theme All nukemods themes have matching phpBB styles that you do not separate.
Once uploaded, change your theme under your USER ACCOUNT preferences FIRST.
DO NOT CHANGE THEME UNDER YOUR ADMIN PREFERENCES UNTIL AFTER YOU HAVE TESTED TO SEE THAT THEME WORKS FIRST UNDER YOUR ACCOUNT!
