Directors' pages don't work

If I click on a director’s name, the list of their films doesn’t show up.

Examples:
https://beta.icheckmovies.com/movies/?filter=director%3Adavid%2Bfincher (David Fincher)
https://beta.icheckmovies.com/movies/?filter=director%3Afritz%2Blang (Fritz Lang)

It works for me, but I get this link: https://beta.icheckmovies.com/movies/?filter=director%3A’david+fincher’
The director’s name gets put in quotes like so: director:‘david+fincher’

Maybe @Marijn can shed some light on this.

Yes, I can. The ‘old’ beta used an encoded + (%2B) between the first and last name of a director and the ‘new’ one just uses a +, so that’s why parsing failed. I’ve fixed it by supporting both (+ and %2B), so it should work now
