Wow, no matter what I do, this file which I’ve converted to PNG shows up as JPEG. At first I thought Preview had done a bad conversion job, but then I used Affinity Photo which should be trustworthy.
I don’t believe I changed that setting since it doesn’t have the ‘reset’ option by it.
When I upload a different image which is a PNG I see the type sticking. There’s something about this file which Discourse really wants to convert. Ideas?
