Well, that is peculiar. I know the system goes out and checks all the entries to make sure they are valid and perhaps it didn't think some of yours were valid. That is all I can think of. I don't even know if I can check and see what might of happened, that is just my best guess.
Could it be related to cookies? Cuz I crap clean my machine often or maybe the ad blocker, never happened before though. And no, I do not try to make more entries illegally.
Honestly I'm not sure. This is only the second time we have used Gleam to host a contest. The best thing would be to contact them directly. gleam.io
Did it with .jpg included...waiting for answers
