Fatal error

Hi,
you should have this function as demonstrated by the core documentation (since 2.0.3):

https://codex.www.ads-software.com/Function_Reference/wp_get_current_user

Which versione are you running?

Cheers, Luca

As suggested here try to :

You open capablities.php and add require_once(‘pluggable.php’);
(but you need to change those quotes to single quotes) right after the opening <?php tag at the top of the file.

The reason I say its a bug is that there is no way we should get to the point that capabilities has been loaded but pluggable hasn’t.

Hope it helps.

Luca

Thanks, I will try today.

Ok, let me know if you succeed. It seems a WordPress bug, but I’m not sure.

Luca
