All of a sudden (it had been working for many months fine), when i try to get my news headlines in RSS Reader for my two feeds i get this error: 'feed contains a XML syntax error. the remote server returned an error: (404) not found' it is also doing it for one other feed i am subscribed too (i did not build this one) anybody know what to do? why did it just stop working? thanks.
Without the URL of the feed we can only guess. The first thing to check is to make sure that the feed is still on your site - maybe an error in the script generating the feed has caused the feed to disappear. Another place to look would be at any htaccess files. Again these are just some stabs in the dark without more information.
I've checked your .xml file with the unix command "xmlwf" and looks good. Your error 404 maybe was a temporary downtime on your server. You can try removing the DOCTYPE declaration.
i removed the doc declaration and it worked...any idea why that would cause it to stop working? it had always worked before with it in there....
No idea, but I have a site that works with many .xml files (some retrieved from external sites via web services, and other self-mades with perl) and never used the doctype declaration.
