Error Envato Wordpress Toolkit

Hi,

I’m trying to update the theme Vega using the Envato Wordpress Toolkit but it returns this error when I start the theme update:

Warning: function_exists() expects parameter 1 to be string, array given in /web/htdocs/www.xxx.it/home/wp-admin/includes/class-pclzip.php on line 1766

Thank you very much for your help.

The Envato toolkit doesn’t work right now, they’re working on an update
