I was in the middle of a third fight with Senor Fuego when there was a page error showing mysterious coding. Since then I've been unable to battle. Even though my battling pet has full health, happiness and health I just get told "Oh no! None of your pets are eligible for battle. You might want to make sure that they're well fed and happy!"

- did you go to the status page to see if you are stuck in a battle?

you likely double clicked the attack button and got the random code page. yeah do what said and go to the status page here and enter the battle from there

Thanks. That worked.
