Hello Alex
I’m very sorry, that I didn’t respond to this support thread.
I have some news for you (and all the others):
1. The API I used is down, so your plugins won’t work at the moment
2. Riot Games released their own API *woohoo*
3. I will release a new version of this plugin in a few weeks
4. The new version will be more comfortable and will have its own menu on the left side of the admin panel. It will also make use of a database, to ensure data availability, even if the API is down.
Cheers
Klemens
