Google webmasters tools tells me I have a number of redirect errors on my site in the format:
My site uses a custom permalink structure which is simply:
If I visit one of the error pages, I get a message telling me the page has a redirect loop.
The numbers are NOT numbers for posts currently on my site - in fact the database item 7963 is an email address.
Can anyone explain what is going on here and whether I should worry about it or just let it go?
