Chapter has no pages!

[GolD_Lip]

I uploaded a chapter with filled zip file and after uploading,when I open it says "Chapter has no pages",not only for me,everyone also.

I tried reuploading,but the same message everytime. This isn't my first upload.
Previously I had uploaded same way without any problem,just this time.

Solved by discord support!
Just the file inside zip had a space before text,so that created the fuss.
