Why can’t I post to meme contest?

works for me and a few others. try using a different browser or disabeling all plugins?

If you have already entered a week. That week is void. This might be the issue . Make a new week or add it to a diary. It doesn't have to be a meme diary. Just a diary.. Give this a go..

I would have to put my money on killer bees

If you mean that it won’t show you certain ones after it takes you to the pictures to pick from? For me it only shows my first few pictures in each diary week. I had to go rearrange and put the one I want to post somewhere as a first or close to first picture in week. If this isn’t what you were meaning disregard and my bad

Probably broken like the photo contest.
