I have a design I’ve created but when I try to apply the tar.gz I’ve uploaded I get the error “No Valid Parse File Found in Archive”.
Can someone have a look at http://webdev7.otago.ac.nz/static/Default.tar.gz and see what I’ve missed.
The parse file works fine if I create a new design, edit the parse file and paste the contents of the parse.html file in.
There is a "Default/" folder in that tarball – recreate it with the files directly stored.
OK, I got it uploaded and applied correctly but my CSS files are showing as plain text files and not as CSS files and as such I can't use it in a design customisation.
Correct. Static CSS files that are uploaded as associated files of a design are uploaded as Text Files. If you want to create a full CSS File asset, you need to do that as a separate action (CSS File assets have their own import/export screen).
Why are they not processed as css file assets or even have the ability to convert them to css file assets? Seems a bit obvious to me.
CSS File assets are completely independent of designs. They already have their own import/export system which is designed to import/export the entire CSS File with associated images. CSS File assets are only used in certain circumstances. Most times, you don't really need them (and the can be more processing intensive than just a plain file, depending on configuration). We have purposefully kept them separate for this reason.
