Last year I had a WP installation for my blog which was fine. I went offline and now installed a clean new version of WP, latest version.
The default 2014 theme had a Sample Page and a Hello World post. They show up fine when I clicked on them.
I went on to customize my site entering data, same theme. Following the instructions I deleted the Sample Page (rather than editing it) and created a new one called About. Did a sample post as well.
Well, Now when I click on the link that should display my About page (as it did with Sample Page) I get a new browser tab with an EMPTY blank page, no markup at all!
I created a new post and it does appear in the landing page but when I click on its link I get the same result, a new browser tab with a blank white page with no markup.
For the sake of testing I switched the theme to 2013 but the problem is the same.
In my old WP installation I could post and create pages and they displayed fine, what is broken now?
