Hi,
you have extended the Deadline to Monday, October 8, 2018 UTC
but on designers' side Project status looks - Closed (Pending Selection) thus new designers can't submit their ideas

Maybe you see project status as "Open - Deciding" from your customer account
yet if you put (+enter) contest link in browser not being logged in the account -- then you see - "Closed (Pending Selection)"

???

Hi please tell this to design crowd as i cannot fix this

If you contacted designcrowd support until the deadline (Saturday, October 13, 2018) --- they would fix it. But now it's late.
