Search Not Working / White Space in Slider

Hello,

My website search isn’t working. Whenever I try to search for something, the search results display nothing. Can this be fixed somehow, please?

Also, whenever I load the website, the slider always has white space on the right. See screenshot here: https://prntscr.com/nx998c. Is there a way to fix this as well?

Thanks.
