Jessica,

Is the page(s) in question indexed by Google? I

I would recommend trying another site crawl tool like Xenu Link Sleuth, GSiteCrawler and see if they are able to crawl the site without issue. Could also be something to do with your hosting company trying to prevent Denial of Service (DOS) attacks... If you want to send me the URL I am happy to crawl it for you with one of these tools.

seems like your website is blocking access to the file. A few questions:

1. Are you blocking robots in your txt file from this url?

2. Do you get the 403 erri when you manually visit the page?

3. What CMS if any are you using? If it is Joomla we've seen some strange things happen with some of the security modules when using crawl tools such as GSiteCrawler.

Is there another folder on your server called resources? If so that maybe the problem. See this thread...

I did run Xenu on your site and experienced the 403 error on that page only. There were other 404s that need to be fixed as well FYI,,,
