Trouble with uploading a chapter

[helkitty]

I have been having trouble with uploading a chapter of a manga that was downloaded from Google Drive. As far as I can tell, they are all just regular zip files with .png but for some reason one chapter cannot be uploaded. It always comes up as an error. I had to extract and re-zip a different chapter that had the same problem and that worked fine. I tried doing the same trick on this chapter and the upload only comes out as a black screen on the reader. Does any one have any advice?

Send me the zip, and i'll take a look what could be wrong with it.
