How to display shop sidebar on product category template of WooCommerce?

Unfortunately there is no option for that out of the box. You would need to manually customize the code in "/includes/plugin-codes/plugin-custom-functions.php" file.

Please find "uxbarn_wooc_theme_wrapper_start()" and "uxbarn_wooc_theme_wrapper_end()" functions in the file and look for this code:

if ( is_shop() ) {

Change it to:

if ( is_shop() || is_product_category() ) {

Make sure to edit the code in both functions. Now your product category template should also display the shop sidebar.
