Fatal Error

Hello Martin Gibson & WP CUSTOM ADMIN INTERFACE team,

first of all: I love your plugin and am actively using it for over a year now.
Thank you for your great work.

Still, I came across an error today. So far, I’ve changed some tiny things on the site for all other users than my own (some label name modifications in the wp admin left menü). After doing so, the site worked just fine for a few days. Now I’ve activated caching (WP Fastest Cache) and al lthe sudden, I can’t access the wordpress site:

Fatal error: Uncaught Error: Call to undefined function wp_get_current_user() in /var/www/vhosts/example.com/httpdocs/wp-content/plugins/wp-custom-admin-interface/wp-custom-admin-interface.php on line 247
