Logo Disappeared with Minification

I ran the minification and cant figure out how to get my logo to show up again. I honestly have never been able to use Hummingbird minification on any of my websites because it usually breaks them. I dont know how to get my logo to show up again and still be able to reap the benefits of the plugin.

Also, it seems like my rating on gtmetrix went down after minifying. It says I still have a bunch of render-blocking javascript and css above the fold but I dont know how to remove them. I moved a couple to the footer but it still shows they are render-blocking.
