So I have this code that gets messages and every 4 hours it posts a random message
I tried to post on facebook using this code few hours ago and all worked fine.
I did some tweaks and tried to run it again and I'm getting this error Application request limit reached
I tried to post a simple thing on facebook and still the same problem
with this code

import fbconsole as F 

F.AUTH_SCOPE = ['publish_stream'] 
F.authenticate() 
status=F.post('/me/feed', {'message':"HI!"}) 
F.logout() 

>and still the same problem
What can I do to fix it?
Thanks!
