Many of my plugins read from XML or RSS feeds. In these cases, I read the files using the PHP file_get_contents() command. However, if you get the following error…

Warning: file_get_contents(): URL file-access is disabled in the server configuration

..then this means that your PHP is not configured to allow this command.

If you can, edit your php.ini file (usually located in /etc/php.ini) and make sure this line is in it:

allow_url_fopen = On

If you can’t edit php.ini, you can try the following…

If you don’t have one already, create a file called .htaccess in your root folder. Now add the following line:

php_value allow_url_fopen on

If that doesn’t work then, well, that’s probably down to restrictions by your host.

Combining usefulness and something that’s popular and “now”, it’s my Simple Facebook Link.

Simple Facebook Link displays a link allowing you to share posts and pages with Facebook users.

You can view more details and download it from the official WordPress site, or from it’s official page on this site.
