Rewrite on custom post type permalink not working?

Question

My theme has a custom post type called 'portfolio'.

I want the url to display 'projects' instead. I've change the rewrite on the register_post_type function to 'projects' but it doesn't change the permalinks...

'rewrite' => 'projects'

How can I fix this?

Answer 1

rewrite accepts a boolean or array, try:

'rewrite' => array( 'slug' => 'projects' )

make sure to visit your permalinks settings page to flush rewrites after you make the change.
