I'm using the following short code
[wp_rss_aggregator date_before='<h2>' date_after='</h2>'] in a page and the following error message is returned at the top of the page:
Warning: file_get_contents(http:) [function.file-get-contents]: failed to open stream: No such file or directory in /home/directory/public_html/wp-includes/class-feed.php on line 88
.. followed by the RSS stream.
Is there a quick fix for this?
