Error using nginx : Undefined index: dirname

I've tried setting up on a Raspberry Pi using nginx, but I keep getting this error when trying to use any of the taxonomy links from the blog skelton package, e.g. http://raspberrypi/tag:journal

Whoops \ Exception \ ErrorException (E_NOTICE)
Undefined index: dirname

Anyone got any ideas what I'm doing wrong? I used the setup as described here: http://www.nirokato.com/blog/raspberry-pi-powered-by-grav

I've tried setting up the same blog skelton using MAMP on my Mac, and it's working fine, so this is more likely to be a nginx config issue, but I don't know where to start looking.

Are you using the latest Grav version. This very issue was fixed recently.

Ah-ha. The blog skelton package is not up to date - I (wrongly) assumed it was. Done a selfupgrade now and all is working fine.

Strange, the blog skeleton should of been up to date also, i'll double check that later. Glad you got your issue sorted :)
