Fatal error: Call to undefined function pll_current_language() #21

Hi,

Awesome plugin you made here! I've just activated this plugin with the latest polylang beta (1.8beta3), and got the message

Fatal error: Call to undefined function pll_current_language() in (...)polylang-slug\polylang-slug.php

I added 

require_once( PLL_INC . '/api.php');

at the top of the file, which seems to fix it. Any idea why this is happening?

Maarten

On what page are you getting the error?

grappler commented 8 years ago

Could you try the latest version and see how that goes?

The same happens with the latest version.

Thank you for the call stack. I was able to replicate the issue and fix it. It was being caused by WP SEO.
