Can't upload to

I seem to be having trouble where I put in a .zip file in the bar, but the upload button doesn’t work.

I think it has to do with the retarded ass poll because when I click “vote” it appears to try, but tells me the file wasn’t a zip file.

I use IZarc instead of Winrar because Winrar is terrible in my opinion. I think that could be causing problems with it, but I don’t know.

Any help?

It does the same with me and it is a zippy file I triple checked
