Thanks, everything is working fine again!
Theme was updated today.
Added a user account just in case you can help out on that front. Thanks!
Disabled plugins, and it is still not there. :0\
We tried emptying our browsers and installed a new browser just in case. Still no slider.
My slider is gone on the homepage too.
I switched the widget out in the meantime since my client wants their christmas photos to display on the website right now.
