MODx encountered the following error while attempting to parse the requested resource:

PHP error debug
Error: file_get_contents(http://www.ventoline.co.uk/blog/index.php?id=9) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error

I have deleted the id=9 page, commented the line in question, no difference, would anyone where the problem comes from?

Thanks for your help

Snippet code is passed through the PHP eval() function by the parser, and the error is occurring at line 120 of the snippet or plugin code (not the document.parser.class.inc.php code). Line 770 of document.parser.class.inc.php is the function to evaluate snippets, so this is a snippet that is causing the problem.

It is likely that your server is configured in such a way that opening URLs as files is not allowed:

A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the List of Supported Protocols/Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.
