I have been tweaking with my site and I really like how it looks now, however my search bar no longer works and the menu bar doesn't stick to the top when I scroll down. I haven't changed anything to the original theme, just some css. I tried reinstalling the theme and disabling all my plugins and neither fixed this problem, so I’m not sure what else to do.
Anyone know how to fix this problem?
Here’s my site: http://julesdiaries.com
Another weird thing is that it works when you click categories or posts, it’s just the homepage that it doesn't work in.
