Google sitemap indexing problem, 404

Hello,

I've got a specific problem I've never seen before. One of our side projects, pipisgames.com. It is almost non-indexed (check in google "site: pipisgames.com", only 27 pages indexed, only the homepage and 2 'handmade', non wordpress pages indexed well)

I've uploaded a sitemap to webmaster tools to get the pages indexed (site got more than 1500 pages)

Webmaster tools googlebot gets 404 problem on ALL pages. I've checked it in all browsers, all pages works normally. I've checked robots.txt and page headers for "noindex" tag, but found nothing.

Any idea what could possibly happen ?

Thanks for your help.

 

Can you give some example URLs Google says respond with "404 - not found" you believe are wrong?

For instance I checked:
http:// pipisgames .com/2011/04/attaque-zombie-3d/

listed in in your XML sitemap::
http:// pipisgames .com/sitemap.xml

and your website/webserver responds with "404 - not found"

 

Maybe it's good just to wait until it all scanned again. I still have some data showing on Google and webmaster tools that was crawled like a few months ago.

 

Thanks for the helps, problem solved. I've changed the wordpress theme to a new one, and indexing started immediatelly.

 

I think your website haven't proper URLs.

 

The problem is when I redirect all the error 404 to another page the internet browser detect that my website has redirect loop. After I delete the plugin folder in my cpanel then it’s okay.
