lost facebook logout button while testing on device -

any 1 have experience on testing application link facebook.my logout disappear while testing on device.but in simulator work fine.

it's possible you're logged out on phone resulting in logout button disappear. have login button? generating login\logout url? simple debug see if you're "logged in" or "logged out".

if you're using xfmbl tag login , logout has been depreciated.

possibly duplicate of facebook logout button not showing

it may case sensitivity issue on file names images or different format phone doesn't support.

check: images showing in simulator not on iphone device
