Thank you for the quick response. Yes, I was importing images and data from a google sheet in which I was pulling images within the cells (=IMAGE(*https……jpg”). I deleted all of that and downloaded the images. Then uploaded them to my WP media library.
I am manually adding images in the TablePress cells by selecting the cell (insert image) then selecting an image from the library. The image is still appearing. I also tried just copying the image url on my server and pasting that into the cell. It also does not show.
Any other ideas?
