Okay, I am completely giving up now. I have been trying for last three hours to upload a 19 Mb file and every time I get an error message after the file is uploaded. (yes, it takes up the time to upload, an error message pops up. FYI, it is a zip file with an ai and jpg file. I uploaded one file before it. This was the second one. If anyone can help with the issue, it will be of great help.
Without seeing the file it's impossible to troubleshoot. The error message is appearing because something is not compliant with our requirements.
Is the jpg in the .zip folder at least 15 MP in size (MegaPixels not MegaBytes)?
Are there any other files in the .zip besides the AI and the JPG?
