I got warning in google webmaster tool for my site and msgs in dashboard are 0. How i will know what kind of warning it is? And how to get back good status.
Strange.. anyway, I don't think it's something to worry about if you didn't make any changes. I usually get warnings when my site is taking too long to load but that usually fixes on its own. Why don't you wait it out a day or two, maybe the warning will disappear?
Not at all Just an error with your sitemap. It's normal, happens all the time. You could try removing your sitemap and uploading an updated one if you're concerned. These warnings are usually related to Google crawling your site. I think I read somewhere that if it's a serious issue they'll contact you through Webmaster Tools messages (I could be wrong though).
thanks nora one more thing how i can scan files for trojan horses and viruses at server. or how a user will know that this site is sending virus. oh GOD i did a big mistake someone told me that my site has trojan horse, and i delete my all the site just for saving my adsense account. oopsssss! i lose my db too.
Wow.. I think it's better to contact your host in a situation like that, maybe they have ways to detect and get rid of it. Don't let go of your backed up database though.
How the virus entered to your server ? .. what about the file permission on your server , 777 access to your files may cause serious risk of errors and sometime it may get virus ...
It's a sitemap error, just remove the old one then create and upload a new one... and you will be fine. However once you see an error in the WMT click on it for more info
i get my site back and submit new sitemap so problem has been resolved. THANKS to all of u specially Nora
