@russsaid Yes, this is the first evidence that it hasn't - I'll take yet another look! Very elusive bug.
Challenge fixed up now, and surplus games removed as they were all undeveloped.
I have a theory.
In the process of constructing the challenge I left the top row vacant. It was easier just to remove those names. In all the other challenges that I have created the vacant rows were always beneath the rows filled with players names. Could that make a difference?
Edit: Please could you get rid of the blue banner for the LFC Supporters clan. You would be surprised how much pain that causes me. Don't know why I can't upload an image to it, but that just directs me to a blank screen when I click upload. If that isn't fixable just replace it with my profile banner. Please, anything but blue.
Your banner image is probably too large (file size)
Can you shrink it and try again? If you do not believe this is the case, let me know, and we can arrange for your to email it so I can take a look.
For a quick fix, create a tiny red square jpeg in MS Paint, then upload that.
The file I try and use is 990 x 100 and 44 kB so should work. There is also the same problem if you try and upload anything else. It just shows a new page in internet explorer which is completely blank. This is only for the banner image.
Edit: have also tried with plain red (jpeg and png) exactly the same happens.
