    Hi Chouby,

    I downloaded my production server WordPress installation, which it’s still using Polylang 1.1.6, into my testing environment.

    Right after updating it with Polylang 1.2.1, and then trying to navigate to another page inside the WordPress administration side, I get a white page and this server error logged entry:

    It’s not a show stopper for me, since I’m still using Polylang 1.1.6 at the server, and quickly reverted the upgrade modifications in my development environment, so I can wait.

    Thank you, Chouby!

    This get_current_screen() function is terrific. Everybody (including me) assumes it is always available… when it is defined quite late. Let’s try to delay the update a bit later (after get_current_screen is defined).

    Could you go in polylang/include/upgrade.php at line 329 and replace

    add_action('wp_loaded', array(&$this, 'wp_loaded_upgrade_1_2_1')); // once wp-rewrite is available

if (did_action('wp_loaded'))
	$this->wp_loaded_upgrade_1_2_1();

    by

    add_action('admin_init', array(&$this, 'wp_loaded_upgrade_1_2_1')); // once wp-rewrite is available

if (did_action('admin_init'))
	$this->wp_loaded_upgrade_1_2_1();

    Yep, that solved it!

    OK thanks. I’ll include it in the next release.
