Fatal Error in WordPress WooCommerce theme "Call to undefined function wc_get_theme_slug_for_templates()"

Question

I am new in WordPress. I am trying to make e-commerce site. I have used plugin WooCommerce and a Woocommerce theme.

My WooCommerce Theme Menu Bar look like:

All links of theme menu working except shop and I am getting this error at the end of "Shop" page:

Error Description:

Fatal error: Uncaught Error: Call to undefined function wc_get_theme_slug_for_templates() in C:\xampp\htdocs\wordpress2\wp-content\themes\vw-ecommerce-shop\woocommerce\global\wrapper-end.php:23 Stack trace: #0 C:\xampp\htdocs\wordpress2\wp-content\plugins\woocommerce\includes\wc-core-functions.php(195): include() #1 C:\xampp\htdocs\wordpress2\wp-content\plugins\woocommerce\includes\wc-template-functions.php(400): wc_get_template('global/wrapper-...') #2 C:\xampp\htdocs\wordpress2\wp-includes\class-wp-hook.php(286): woocommerce_output_content_wrapper_end('') #3 C:\xampp\htdocs\wordpress2\wp-includes\class-wp-hook.php(310): WP_Hook->apply_filters('', Array) #4 C:\xampp\htdocs\wordpress2\wp-includes\plugin.php(453): WP_Hook->do_action(Array) #5 C:\xampp\htdocs\wordpress2\wp-content\themes\vw-ecommerce-shop\woocommerce\archive-product.php(110): do_action('woocommerce_aft...') #6 C:\xampp\htdocs\wordpress2\wp-includes\template-loader.php(74): include('C:\xampp\htdocs...') #7 C:\xampp\htdocs\wordpress2\wp-blog-header.php(19): in C:\xampp\htdocs\wordpress2\wp-content\themes\vw-ecommerce-shop\woocommerce\global\wrapper-end.php on line 23

Please help to resolve this issue.

Answer 1

Ok, the error is telling you this:

The error comes from this theme file:

\themes\vw-ecommerce-shop\woocommerce\global\wrapper-end.php

Line: 23.

In that file on line 23 the following function is called wc_get_theme_slug_for_templates() but at that point it's not (yet) available. The function should be available though, because it's a valid Woocommerce function, see here.

Can you update your theme? It's always important to keep the theme up-to-date with WooCommerce, otherwise problems will arrise eventually (and probably sooner than expected).
