Heading styles not showing

Hi,

When I create a post the heading styles show in the actual post page, but not on the front page which shows most recent posts.

For example actual post here:
http://gumsek.com/my-first-post/ – the word “test” is h2
but on the front page:
http://gumsek.com/ – the word test is a p tag.
Any changes I make to font headings in blog posts they only show on the actual post page not the front page.
I’ve tried deleting the theme in WordPress and reuploading the theme, problem continues.

I originally wanted to use the theme font settings to include the Raleway font, so I edited
class.options_machine.php to add the Raleway font to the theme font setting page:

$faces = array(‘arial’=>’Arial’,
‘verdana’=>’Verdana, Geneva’,
‘trebuchet’=>’Trebuchet’,
‘georgia’ =>’Georgia’,
‘times’=>’Times New Roman’,
‘tahoma’=>’Tahoma, Geneva’,
‘palatino’=>’Palatino’,
‘Helvetica Neue, Helvetica’=>’Helvetica’,
‘PTSansCaptionBold’ => ‘PT Sans Caption Bold’,
‘PTSansRegular’ =>’PT Sans Regular’,
‘Raleway’ =>’Raleway <- Added this line here

Seemed to work ok, but then noticed the blog posts and font setting weren’t always showing right, so I changed it back. Everything was ok again.
But then, I discovered the post title h2 tag wouldn’t respond to font settings in the control panel, and I thought it was somehow because I added this line to class.options_machine.php.
Later I discovered that the font setting don’t work for post title h2, and found a css fix here. However it took me ages to find this fix, and so first I deleted the theme and reinstalled.
Ever since the reinstallation of the theme I’ve had the blog post problem, I’m wondering if th edatabase or something is corrupt it ins’t working properly.

Is there a simple way to get blog posts working properly so they change in the post also shows on the front page?
Or do I need to reinstall the theme – this is easier said than done I tried before and there was all sorts of data left. I may just do a complete blank site reinstallation in my hosting account, if there isn’t a better way. If there is a better way though can you possibly let me know, thanks
