I have installed the jquery theme switcher. Overall it seems to be working, but when I make a theme at ThemeRoller, I don't have any of the directory structure mentioned in the user's manual. I don't have a folder with the name of theme, just a "jquery-ui-1.11.4.custom" folder with an "images" folder and "external" folder inside along with jquery-ui.min.js and jquery-ui.min.css, but there is no jquery.min.js. There are several other files: jquery-ui.css, jquery-ui.js, jquery-ui.structure.css, jquery-ui.structure.min.css, jquery-ui.theme.css, jquery-ui.theme.min.css.
Also, when I add a theme all of the columns and header changes, but there is no effect on the products in the centre. Is this normal? Would I be better to go with the bootstrap?
