Lightbox background remains

Hi. I launched my website and then decided I did not want the light box. So I deleted it. Now, a few seconds after the website launches, a blue screen appears, and I cannot figure out how to eliminate it.

I have to click on the blue screen in order for the website to appear again. I tried adding a button to the blue screen that said, “Click here” so someone would know what to do, but that did not work.

I’ve checked Youtube and information about lightboxes, but I cannot find anything that addresses this issue.
I’m using Wix Editor
