I get this msg (the doc contains a link...) and have read the other blog about going back and upsampling, however, how do know which images is the problem?
Thank you for your reply. Just to let you know that I used the offending image in more than one web site. However, one three of the sites, it never showed the colored checker board so I never knew that was the problem. Yet, when I went to one site, the checkerboard showed up and I corrected the problem. Then I went back to the other two and even though the checkerboard did not show up, I corrected that image and when I did, saved, and reopened, it worked. Thank you.
I am getting the same message. I went to my assets panel and looked for the colored square and there is no such icon. I opened all my pages and went through each asset one by one and checked for upsampling. I did not find anything. When I go to export the site, I get the warning.
Is there another method to check where the problem is coming from?
