Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?

A customer is using the <base>-tag in an odd way: <base href="http://domain.com/1.0.0/1/1/"> My own theory is that the subfolders are added as the root because of revision control. CSS, images and internal links are used like this:
internal link I ran a test with Xenu Link Sleuth and found many broken links on the site, but I can't say if it is due to the base-tag. I have read that the base-tag may cause problems in some browsers, but is this usage of base-tag bad in some SEO-perspective? I have a lot of problems with this customer and I want to know if the base-tag is a part of it.
