Doesn't appering anything on LCD display

[cb-sah]

Hello Sir,
I have tried your code but it is unable to print anything on the display.
I have tried some codes "hello world" and "connecting to google or facebook"; these all worked fine but when I uploaded your code by changing the id of the page it doesn't showing any thing on the LED.
So, please help me.
Thank you.

Hello,
If you look at the code you can see that there are two parts of the URL

The domain:
http://api-read.facebook.com/
The page with arguments part:
restserver.php?format=xml&method=fql.multiquery&pretty=0&queries={%22page_info%22%3A%22select%20name%2Cfan_count%2Cpage_url%2Ctype%20from%20page%20where%20page_id%20IN%20(27479046178)%22}&sdk=joey%20HTTP/1.1

You can test if facebook returns you the right code puting it into a browser:
http://api-read.facebook.com/restserver.php?format=xml&method=fql.multiquery&pretty=0&queries={%22page_info%22%3A%22select%20name%2Cfan_count%2Cpage_url%2Ctype%20from%20page%20where%20page_id%20IN%20(27479046178)%22}&sdk=joey%20HTTP/1.1

You must change the id for the id of your page.

If the response is not correct there is a problem with your page. No solution.

If the response is correct there is a problem with the code, perhaps some deprecated funtion.

The code was ok 3 years ago. This is an old project that i have abandoned.

Sorry.

Facebook has deprecated the API that this project uses.

The current (as of May 2017) FB integration would require a web server in which to put the current SDK and execute whatever you'd like and return only what the Arduino wants (a.k.a. <fan_count>#####<)

Thanks for this project man. It got me started into Arduino. <3
