There seems to be a greyish/blue overlay. You can see it at the top of the image. No matter where I go, I cannot remove it. It looks to be the background showing through. I am newer to squarespace, but have been a hand coder for years.
I have attempted to
Save as a .jpg (made sure it was pure white before exporting it in photoshop)
Save as a .png (made sure that I turned off the transparency)
The template I am using is Colima. This has happened before on another theme and is extremely annoying.
