Part of my Webpage does not Link

[RandomGuest]

For some reason when I hover in a specific area (the left top corner) of my webpage, it does not want to link. It is consistent when I go through my other pages of my website.

More Info:
I modified a tumblr theme, and maybe I messed something up.

Hello RandomGuest,
Yes, maybe you did. If you want help with it though, you will need to give us a link so we can see the problem.
