Facebook登录卡住空白页

Question

Note: when i got the blank page ,i tried to view source in chrome,then i got the source page of the heading location page

This is a Facebook login application page, the problem is it gets stuck to a blank page,no errors is shown.just a blank page,when i click refresh the page is redirected to the page i want,given in the location .

Insertion is also sometimes done 2-3 time when refresh is done.

How to solve this issue?

Blank page means there're an error on your php script (missing bracket, error on database commands, etc).

if you're hosting that page i suggest for you to see the error_log on the folder inside your hoster
