Why I can not see my photo albums?

Hi, I accept achieve the Access Token but I had two problems:
1) After installing the module, required PHP 5.3 (my hosting is 5.2). I solved it by editing the file "facebook_album_fetcher.info" and reelplace line php= 5.3 for php= 5.2

2) I can list my albums by clicking the FACEBOOK ALBUM LIST option of the Tab, my browser displays the following:
Server Error

The website encountered an error while retrieving the http://www...../?q=admin/config/content/facebook_album_fetcher/album_list http://......./?q=admin/ config / content / facebook_album_fetcher / album_list. It is possible that this is inactive due to maintenance or has been configured incorrectly.
HTTP Error 500 (Internal Server Error)

Why I can not see my photo albums?
