How can i find the app that is causing me to only push deny and not allow on apps

[Android Central Question]

Like on Facebook it asked me to allow or deny to add pictures and I tried to click allow bit it didn't work I could only push deny

If it's on allow, you can't choose allow again, it's already allowing.
