Changing Font Style in Flexsqueeze

Hi

I have a version of Flexsqueeze and for some reason the font style throughout my blog (blog posts and title posts) has changed to to the same style. I have changed the settings on the flexsqueeze theme options to a different font and size but it doesn’t change it. If I change the post title size in my actual posts to a heading font – they appear smaller than the normal font when I view my blog. I have even tried to put the html code into my blog post but it just seems to ignore anything I put.

I changed the theme of my blog – delected the flexsqueeze theme and reinstalled it – but when I went back to that theme it just put everything back as it was.

Blog is: https://raybarnett.info

Any suggestions please?

Thanks
Ray
