Hello, It seems I keep getting the "Something went wrong! Make sure your images are in the pages folder! See console for details." I'm sure I put png files in the pages folder. Do I need to number it a specific way or link it to the original file some how? I have exactly 8 pages, changed settings to template 1, and my pngs are 421x595px. Is there anything I'm doing blatantly wrong with what I've described?
