Updated a post but not showing on my homepage. And 2 more question

I have multiple questions. I don’t know which category it fits in. So I’m posting here :slight_smile:

#1. I updated a post. It shows in my admin area, but that post is not updated on my page. What could be the problem?

#2. How & from where do I change this GRAV thing?

#3. Instead of listing all, how can I make it to 1,2,3,4,5… next page & then 6,7,8,9,10…next page?

Please kindly help :slight_smile:
I finally managed to copy-paste my blog
