Messed up sub-directories? URL adding another level.

Hello there,

Wondering if anyone can help!

Had everything on my site working fine yesterday. I log in today to find that the URL is wrong for a certain group of pages.

Namely, when I create pages under my “portfolio” and publish them, the URL it creates is as follows:

http://riptiderocknrollbar.com/blog/portfolioentry/test-2/

As you’ll see, that leads to a 404 page.

If you remove the “blog/” from the URL, it points to the right page.

How has “portfolioentry” moved to another folder, and how can I fix this?

Any help would be appreciated!
