I closed the action confirmation (when feeding, playing etc), thinking it would just stop the individual confirm of action. Apparently, it stops the action ability all together. How do I get the confirm pop up back so I can feed my pet now?

Restarting your browser might fix it too, that's been the general suggested fix in Help & Questions when this comes up

I dont have adblock, (though, I should lol) and the same confirmation is still appearing on other sites. I will try the restart and see if it helps. Thank you.

Rebooting has repaired the problem. Thank you.
