Warning: file_get_contents() [function.file-get-contents]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in eval()

I have this warning for a long time and can't figure out how to fix it for a long time. I spent a lot of time searching and looking and until today!

The solution is very simple once I figure out what it was and it was "Remote File Source", you must enable "Remote File Source" once when you do you will get the warning below:

You must enable the File Field Sources, File, Remote stream wrapper modules to install Remote File Source.

Would you like to continue with the above?

Just click "yes" to continue and the warning will go away.

Finally, after all, this time!

I hope this will help someone.
