The link to the allow_url_fopen page on UBBDev is here, basically your host doesn't have the feature allow_url_fopen set to true so content can't be retrieved from off server (checking the SFS API).

As for the FAQ try uploading a copy from your install archive or opening the file in a text editor and ensuring there's proper formatting in the PHP file. Likely, around line 46, you'll find an extra semicolon or something that is breaking the previous entry in the file.
