I have posted the same message below at Google Comunity but have had no
resolution to the problem and found out about here you might be able to
solve the problem details below

I keep getting unsual links google keeps finding, i cant find them with
xenu, my crawler cant find them, but in webmaster tools at google >
diagnostics > crawl errors
I keep getting these errors with my url in front of the com, they dont
exist
.com/%1F
.com/%1Fn
.com/%1F&=%1FC%23%1F=%23%1Fa/%1Fa/%1F%5E
Is this normal? a bug? someone submitting bogus urls to google(this i
think is the problem)? if its the latter is it not my sitemap it sould
be keeping a record of?

I have removed my sitemap and re-added it, but only for more different
variations, i have also gone though every script and every page to
detect lower case format contact-us.php to which should be
Contact-Us.html(does not exist) each time i delete the site map i get
good ranks after resubmitting then something different will appear
lower case something and prevesios errors are not there all new ones, i
have no dead links & valid html that feeds css to serveral browers for
my site to be viewed by most top browsers its all in php with mod
rewrite.

There is also your feed back button that asks how you rate the tool, i
like your tools but if the diagnostics had where the bogus link came
from, like was it from a page that would make it a top tool, otherwise
not much use except to tell u got a problem.

Any kind of suggestions or feed back would really be appreaciated

For example there is a crawl (404) error for

http://news.sawf.org/18620.aspx

We do have a url http://news.sawf.org/Health/18620.aspx included in our
index at

http://news.sawf.org/sitemap4.xml

I have no idea why Googlebot is reading it as
http://news.sawf.org/18620.aspx instead of
http://news.sawf.org/Health/18620.aspx

Additionally, we have many bogus urls in the crawl error list. For
example

http://news.sawf.org/Health/11410.aspx&cid=1106194255&ei=80NWRLW6DZPo...

While we do have the url http://news.sawf.org/Health/11410.aspx, I have
no idea where Googlebot got the url above that it is attempting to
crawl.

I have perused the posts in this group made in the past. Some of these
posts have alluded to the problem we are discussing, however, I did not
find a satisfactory response. May I request someone from the Google
team to intervene?

These days, incredibly enough, we are getting more traffic from Yahoo
and MSN search than Google search!

All our pages our dynamically generated.
Our sitmap index is placed at http://news.sawf.org/sitemap_index.xml

For example, I have the link <a href="24908.aspx">...</a> placed on the
page http://news.sawf.org/Sports/24497.aspx

If you click on the link the browser will resolve it to
http://news.sawf.org/Sports/24908.aspx

I think Googlebot is resolving it as http://news.sawf.org/24908.aspx
instead of http://news.sawf.org/Sports/24497.aspx

If this is so is it something that the Google team will correct or is
it something that I need to fix?

I did go though all of this from the below url to convert it
.com/%1F&=%1FC%23%1F=%23%1Fa/%1Fa/%1F%5E

.com/_&=_C$_=$_a/_a/_^

No scripts run at home directory level
No mod rewrite need at home direectory level only for the extensions
php to html

It is definatly something google(engine) has a problem with.

Is there any reps from google in the forum, to confirm this problem? Or
at least able to resond to give any kind of insight as to the best
approach to rectifying this problem?

Is this particular error, a part of your ranking structure to penalise
websites?

I am still reasearching this furthure, but am having problems with
google dropping my sitemap at the moment. Will retry in 48 hours time

This is still a unresolved issue
