The following solution will work only if you have the file “loop-shop.php” in your wp theme folder.
Solution:
Create a folder named woocommerce in the folder of your current wp theme and COPY the file loop-shop.php in it.
Alternatively you can replace “get_template_part( $woocommerce->template_url . $slug, $name );” with “get_template_part( $slug, $name );” (without quot. marks) in woocommerce-core-functions.php.
This is probably a bug and will be repaired.
