Hi Sanjip,
No, I didn’t “set the ‘Posts page’ from Settings->Reading.”
I Followed the instructions from ” 14) How to setup Blog page ”
I created a new page, called it “Blog”, then chose “Blog Image Large”
But when I created blog posts they werent arriving on the Blog page, so i created a new category called “Blog” and assigned all my blog posts to that category and then all my blog posts showed up on the Blog page. However, so did all my slider posts even though they are not in the “blog” category, they are all in “uncategorized”
