Errore Fatale Qi Addons For Elementor

Ho appena installato un tema sul mio wordpress e tra i plugin richiesti c’è Qi Addons For Elementor, ma provando ad attivarlo mi da un errore fatale in particolar modo questo:
Fatal error: Uncaught Error: Call to undefined function qi_addons_for_elementor_get_attachment_image_url() in /home/customer/www/luciagiannini.it/public_html/wp-content/plugins/qi-addons-for-elementor/class-qiaddonsforelementor.php:226 Stack trace: #0 /home/customer/www/luciagiannini.it/public_html/wp-includes/class-wp-hook.php(324): qi_addons_for_elementor_add_placeholder_image(”) #1 /home/customer/www/luciagiannini.it/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #2 /home/customer/www/luciagiannini.it/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #3 /home/customer/www/luciagiannini.it/public_html/wp-content/plugins/qi-addons-for-elementor/class-qiaddonsforelementor.php(162): do_action(‘qi_addons_for_e…’) #4 /home/customer/www/luciagiannini.it/public_html/wp-includes/class-wp-hook.php(324): qi_addons_for_elementor_activation_trigger(false) #5 /home/customer/www/luciagiannini.it/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(”, Array) #6 /home/customer/www/luciagiannini.it/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #7 /home/customer/www/luciagiannini.it/public_html/wp-admin/includes/plugin.php(693): do_action(‘activate_qi-add…’, false) #8 /home/customer/www/luciagiannini.it/public_html/wp-content/themes/sahel/includes/plugins/class-tgm-plugin-activation.php(1042): activate_plugin(‘qi-addons-for-e…’) #9 /home/customer/www/luciagiannini.it/public_html/wp-content/themes/sahel/includes/plugins/class-tgm-plugin-activation.php(923): TGM_Plugin_Activation->activate_single_plugin(‘qi-addons-for-e…’, ‘qi-addons-for-e…’) #10 /home/customer/www/luciagiannini.it/public_html/wp-content/themes/sahel/includes/plugins/class-tgm-plugin-activation.php(743): TGM_Plugin_Activation->do_plugin_install() #11 /home/customer/www/luciagiannini.it/public_html/wp-includes/class-wp-hook.php(324): TGM_Plugin_Activation->install_plugins_page(”) #12 /home/customer/www/luciagiannini.it/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(”, Array) #13 /home/customer/www/luciagiannini.it/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #14 /home/customer/www/luciagiannini.it/public_html/wp-admin/admin.php(259): do_action(‘appearance_page…’) #15 /home/customer/www/luciagiannini.it/public_html/wp-admin/themes.php(10): require_once(‘/home/customer/…’) #16 {main} thrown in /home/customer/www/luciagiannini.it/public_html/wp-content/plugins/qi-addons-for-elementor/class-qiaddonsforelementor.php on line 226
