I purchased and installed woocommerce page builder, created a product page template, but It is not working on products I’m getting lines of code as error.

I’m getting this.

Fatal error: Uncaught Error: Using $this when not in object context in /home/builxmcz/usmankashif.com/wp-content/plugins/dt_woocommerce_page_builder/includes/class-woocommerce-page-builder-manager.php:482 Stack trace: #0 /home/builxmcz/usmankashif.com/wp-includes/class-wp-hook.php(287): WooCommercePageBuilder_Manager::the_product_page_content(”) #1 /home/builxmcz/usmankashif.com/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(”, Array) #2 /home/builxmcz/usmankashif.com/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #3 /home/builxmcz/usmankashif.com/wp-content/plugins/dt_woocommerce_page_builder/woocommerce-page-builder-templates/content-single-product.php(59): do_action(‘dtwpb_product_c…’) #4 /home/builxmcz/usmankashif.com/wp-includes/template.php(725): require(‘/home/builxmcz/…’) #5 /home/builxmcz/usmankashif.com/wp-content/plugins/woocommerce/includes/wc-core-functions.php(197): load_template(‘/home/builxmcz/…’, false) #6 /home/builxmcz/usmankashif.com/wp-content/themes/wellspring/framework/mo in /home/builxmcz/usmankashif.com/wp-content/plugins/dt_woocommerce_page_builder/includes/class-woocommerce-page-builder-manager.php on line 482
