So today I made a competition in OSM.
A few of my friends wanted to join this competition, but I can't accept them. I tried it on PC (Google Chrome and Mozilla Firefox) and I also tried it on my mobile phone (Samsung Galaxy A5 2017). But when I want to accept/deny my friends for the competition, I get an error every time. On my phone it says: 'Error 404, player not found' and on my PC it says that 'There's something that went wron'.
I would really appreciate help, because me and my friends would like to play this competition!
If there already was a topic about this subject, then I am very sorry. Thanks in advance for the help!
