for some reason the slider for all my blog posts changed, I have no idea why (Specular). Where can I change the post slider (static, not changing, just one picture) for all my blog posts?
You have not assigned any page as blog page. Can you please send us the link of the page you are referring to? Did you make any update before the slider change?
Sorry but i don’t understand very well. I see you have set up page header in posts. This is indeed a static, not changing, just one picture header. And you can set it up to be different for every post, in posts General Settings > Page Header Options > Page header background.
Let us know.
