Why can't I add Pokemon into a Gym?
When adding a Pokemon into a gym, it says 'Error' and kicks me out. My Pokemon are at full health, I've tried with different Pokemon, but still nothing. Can anyone help?
Update: It's working now, however it's not the same as some other questions because I'm still able to use Pokestops and capture Pokemon. Just not gyms.
Best Answer
I've had this happen to me several times. It is possibly due to someone else having placed a Pokemon in the gym before you while you were trying to place one.
This causes an error because the gym is now of a different colour or all it's spots are full.

Answer 2
Restart the app. Chances are you'll find you can't place a pokemon in there anymore either due to the gym changing colors or another trainer on your team placed their pokemon in the open slot.
