Header stuck on the left, links no longer clickable, webform no longer working

My blog is: https://thismindbeinyou.com/

I’m not sure when this happened, but it seems like it was after the last update, but my header graphic moved from center to the left. I’ve tried to fix it in both “header” and “theme options”, but in “header” there isn’t anywhere to change the justification, and in “theme options” it is showing that I have it set to “center”.

I have one page where my links are not clickable anywhere but in the first word, which is totally annoying because it seems like most people just click anywhere on the link and have no idea that they would need to go to the first word to click.

I am using a MadMimi webform for subscriptions to my newsletter, and it’s no longer allowing people to plug in their email address. I have tested it on the MadMimi site, and it’s fine (meaning, I can plug in my email addy there), but on my blog, no go.

Thanks in advance for any help you can give me.
