Plugin gera crash no site

Bom dia amigos,

Ao instalar o plugin em nosso site ele crasha completamente. Já reinstalei algumas vezes mas o erro persiste. O q posso fazer?

Segue erro:
“Fatal error: Uncaught Error: Call to undefined function wp_get_current_user() in /home4/gigash14/public_html/gigashop.com.br/wp-content/plugins/woocommerce/includes/wc-user-functions.php:270 Stack trace: #0 /home4/gigash14/public_html/gigashop.com.br/wp-content/plugins/woocommerce/includes/wc-user-functions.php(393): wc_current_user_has_role(‘administrator’) #1 /home4/gigash14/public_html/gigashop.com.br/wp-includes/class-wp-hook.php(286): wc_modify_editable_roles(Array) #2 /home4/gigash14/public_html/gigashop.com.br/wp-includes/plugin.php(208): WP_Hook->apply_filters(Array, Array) #3 /home4/gigash14/public_html/gigashop.com.br/wp-admin/includes/user.php(269): apply_filters(‘editable_roles’, Array) #4 /home4/gigash14/public_html/gigashop.com.br/wp-content/plugins/screets-lc/core/options.php(1589): get_editable_roles() #5 /home4/gigash14/public_html/gigashop.com.br/wp-content/plugins/screets-lc/core/options.php(732): __fn_lcx_render_caps() #6 /home4/gigash14/public_html/gigashop.com.br/wp-includes/class-wp-hook.php(286): _ in /home4/gigash14/public_html/gigashop.com.br/wp-content/plugins/woocommerce/includes/wc-user-functions.php on line 270”
