Answer 1

(You might have already done this, but I can't tell)

I'm a newbie at coding >.> But I'll try my best.

You can try making it so if its not at the login URL, then it won't show the MessageBox.

if(/* Url != LoginUrl */){

//don't show the message box

}

else{

//do show

}

Hi AhmadRock51,
According to your description, this question is about Fackbook SDKs which you can get better support in Facebook developers forum.
Sorry for any inconvenience this may cause.
Best Regards,
