Item reject :(

I’ve been participating for 3 years but have never successful uploaded successfully; Now it seems to be progressing better, but you’re reporting errors that I don’t quite understand (the file is in pdf or html format - meaning the file in “Main” section is there for me to “read me.txt” & I’ve deleted that file because it’s the same as the index).
I hope you will support me so that I can post successfully. I sincerely look forward to your support
Appreciate, thank you very much
