I have a website on website designing and related stuff. http://www.webguru-india.com/webdesign.php But there’s something rather strange going on in Google Webmaster reports. The reports keep on showing “Page not found†errors. For pages that don’t even exist. Although it’s a php page, new html pages are being created on their own. And the reports show these pages (which were never there) and report 404 errors. Up till now there are ~6000 such errors. Why is this happening? How can I stop this? Can someone help? Here is a screenshot. An advanced thanks!
If you click on the 'Linked From' link to the right of each page, does it show if they are linked from your site or from another site?
