Blog Page link is not working?

My Blog Page works http://new.waveeffectfitness.com/blog, but when I write a post it creates a page link like this for everyone of them http://new.waveeffectfitness.com/page-title.

I have tried

Settings > Permalinks
Choose Default.
Save Changes and try.
If it works, try setting the Post Name again.

The post worked but my other pages did not. I reset it and the other pages worked but the post did not again.
