Yes, you can use as many themes as you want and have them change automatically according to which module is displayed. Either use the theme changer module or this script in a php custom block;
$GLOBALS['xoopsConfig']['theme_set'] = "theme_name";
change theme_name for the alternative theme and place the block VISIBLE and without a title to show in the module(s) that you want this theme to change for.
Doesnt seem to work.
I installed the Themes Changer and cannot seem to get it to work. It seems simple enough. No complex settings. No hidden setup reqirements. I am mystified.
Any ideas?
