Well, I'm referring to whatever it is that makes the site look different. I suppose you're right. Themes. But I see no place in the XOOPS admin to upload themes.

Or maybe I'm missing it?

I have XOOPS installed correctly. I want to install new templates. I see some that look nice. I download them, then try to upload them, but get an error message: Errors Returned While Uploading MIME type not allowed: application/x-zip-compressed

I'm assuming its because all the templates are .zip files but the XOOPS upload feature requires them to be tar.gz/.tar files with "a valid XOOPS template set structure."

So, where do I get templates that are tar.gz/.tar files with "a valid XOOPS template set structure?"

Or how do I convert the ones I have?

Thank you.
