Warning Problems After Listing

I am having real trouble with this plugin, I create a listing and after I’ve pressed save it comes up with the following:

Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration in /homepages/1/xxremovedxx/htdocs/app412280853/wp-content/plugins/fs-real-estate-plugin/common_functions.php on line 300

Its driving me mad, as nothing will change, I can’t add new pictures and I really want to use this plugin for my website. I’ve tried uninstalling and reinstalling, using different themes etc.

There is no problem on the actual site, just the backend.

Thanks
