I don't usually use Kumos because I primarily play on my phone, but thought I'd try out the avatar contests today. As soon as I click on "Enter Contest" I get the "Oops something went wrong" page. I double checked that my HA was set to public. Also logged on from my laptop and Firefox, in case it was a phone issue, but same thing.

As an aside, if there was ever an avatar contest that was made for me, it's the monochrome one. I'm just trying to decide which to enter once it's working!

Edit - welp it finally let me enter an outfit but it turned me naked and only entered a naked outfit instead of the one I chose. Looks like I’m not the only person that happened to because there’s another entry with the same naked base.

I came to post this same thing. I keep getting the "Ooops" image and wording. I have checked off and on for the past couple of days, it won't allow me to enter.

There's another error with it now. I just followed a link to look at the entries to vote. One of the entries says it's by me, but it's not. Sorry to whoever's HA that is, because it looks like the only one that was successfully submitted.
