Fatal error with the setup woocommerce

Hi,

thanks for your plugin.

Can you change your function line 121 from functions-extra.php

because i get fatal error when i run the setup of woocommerce, like this :

Fatal error: Uncaught Error: Call to a member function remove_help_tabs() on null in /home/youpain/public_html/**********(private)/wp-content/plugins/disable-blogging/includes/functions-extra.php:63 Stack trace: #0 /home/youpain/public_html/**********(private)/wp-includes/class-wp-hook.php(298): Fact_Maven_Disable_Blogging_Extra->help_tabs('') #1 /home/youpain/public_html/**********(private)/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #2 /home/youpain/public_html/**********(private)/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/youpain/public_html/**********(private)/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-setup-wizard.php(150): do_action('admin_head') #4 /home/youpain/public_html/**********(private)/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-setup-wizard.php(125): WC_Admin_Setup_Wizard->setup_wizard_header() #5 /home/youpain/public_html/**********(private)/wp-includes/class-wp-hook.php(298): WC_Admin_Setup_Wizard->setup_wizard('') #6 /home/youpain/public_html/**********(private)/wp-includes/class-wp-hook.php in /home/youpain/public_html/**********(private)/wp-content/plugins/disable-blogging/includes/functions-extra.php on line 63
