From: Bjørn Erik Pedersen Date: Fri, 23 Nov 2018 08:16:42 +0000 (+0100) Subject: Handle themes in the new file cache (for images, assets) X-Git-Tag: v0.52~18 X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f9b4eb4f3;p=brevno-suite%2Fhugo Handle themes in the new file cache (for images, assets) In the newly consolidated file cache implementation, we forgot that we also look in the theme(s) for assets (SCSS transformations etc.), which is not good for Netlify and the demo sites.
