Glad you resolved it. One of the issues that arose was server-side caching of my style sheets, so no updates were appearing as I edited, even with force refresh and cache dumping through browser and Varnish. I can’t imagine why else that would have started immediately upon update to 4.7.1. I decided to keep the update and build code to resolve errors, since I’m pre-launch and if something is going to break, now is the time to deal with it. Anyway, spent a good while working on server-side caching issue. Found a clean piece of code that resolved it, now I’m able to get back to working on the actual design. The code timestamps the CSS file request so it can’t cache, and you only need to modify functions page. Not sure if it’s relevant to you, but here’s the link as it could help someone else: http://astronautweb.co/snippet/auto-version-css-load-after-plugin/.
Did your site automatically update to WordPress 4.7.1? I installed the update yesterday and my CSS fell apart on category and product pages. Trying to resolve but hitting a wall. Now trying to revert back to 4.7.
