I’ve noticed a really weird problem with the free Interface theme today – it’s started showing only one category on my blog. It used to work as expected. When I use the free ambition theme or the stock wordpress 2015 theme all articles show.
I don’t have any plugins that restrict categories – if I did that would apply to the other themes, which work fine. I have W3 Total Cache, Cloudflare, an SEO plugin, but nothing particularly odd in terms of plugins. All caches have been cleared out. I’ve put CloudFlare into dev mode, which effectively shuts it off.
Not sure how to show images, but here are links – look for the “PTS SEO Roundup” article, which is missing with Interface.
Here’s the interface theme showing only “customer success story” category: http://imgur.com/Y9AaBLc
