Webmaster tools flagged quite a few 404 errors on member only pages on http://www.youngwomeninenergy.com
fyi - one of the urls flagged with a 404 error:
Search engines do not have access to these member pages so I'm a little perplexed as to how this is happening.
The site has been inundated with spam lately. Wondering if perhaps it is possible for a removed member to have triggered the 404 while attempting to navigate the site after their account was deleted.
Do you think that is the cause or something else?
