Changes are not showing up

Hi,

I tried to make a new post on my blog but it wasn’t showing up on the home page.

So I tried editing a few older posts and updating them but on the front end the updated I saved weren’t showing up.

I’m not using any cache plugin and have tried from different computers / ISP’s.

I also tried disabling plugins, and changing the theme but none of this worked, it was still showing the old theme!

What can be the cause of this?

Thanks
