blog page showing only the bottom half of page on mobile

Hi,

I asked this question previously and didn’t receive any assistance……trying again:

When I tested out my nonprofit website on my phone, I noticed that the blog posts are not showing up, because the page is cut off (only the bottom half is showing –the last post). Is this a bug?? This is very problematic as we have a huge campaign starting tomorrow and no one can read the content we are creating from their phones!

Please Help!

Thanks,
Jen
