fopen error On my local server everything works fine but when I install Dynamic SiteMap on my live server I get the following error: Warning: fopen(http://www.google.com/webmasters/sitemaps/ping?sitemap=http%3A%2F%2Fwww.dunlopgolf.nl%2Fsitemaps.xml): failed to open stream: Permission denied in /usr/local/www/www.dunlopgolf.nl/admin/create_xml_sitemaps.php on line 269 There was a problem notifying Google. I have tried setting different permissions on the XML files as well as the PHP files but with no succes. Does somebody have a clue where this error is coming from? I have been searching Google as well as PHP.net but I can't find the solution to this problem. Perhaps some PHP settings??? Or server settings??
