Portfolio page no works

Hey guys,

I noticed a bug or something – I’m no longer able to link to individual portfolio pages anymore. Where the portfolio page used to be it says: Nothing Found – Sorry, the post you are looking for is not available. Maybe you want to perform a search?

I’ve cleared my browser cache and only have Jetpack, Akismet and WP-Optimize as plugins.

Thoughts?
