I wanted to see if fontawesome icons worked in my blog title, so entered one in. Saw it broke, and then tried to remove it. Well now I can’t remove it no matter what I do 
I have removed any custom themes, and hit save, but it doesn’t save. I’ve tried rebuilding my blog a couple of times, still didn’t save. I also have tried to change the theme, but the broken code follows. See screenshots:
Can anyone help me rebuild my blog?
