Posts not showing up after theme install

Hi There,

I used to use the Journalist theme, but this afternoon I thought I’d see if I preferred something else, so I installed another theme.

I decided that I didn’t I didn’t like the new theme, so changed back to the Journalist theme. Problems is that none of my posts are showing up on the front page.

I’ve read a bit and tried to deactivate all the plugins etc, but nothing seems to work.

Does anybody have any ideas please?

Many thanks!
