Hi, I reply in this topic, cause I might have a very related problem. I am busy configuring a shop based on the quickstart package of Bikestore 1.3.1. Now I use a child theme for the custom development and was for an hour or so puzzling how to get News Show Pro t show thumbnails, which it didn't. Upon checking the access rights as you described here I discovered the cause of my problem, but I think it's something in the theme that is should be corrected:
- when working with a childtheme News Show Pro creates thumbnails in the cache-nsp directory of the parent theme, which seems logical to me, but NSP itself searches for the thumbnails in a non-existent cache-nsp directory in the childtheme. I think it is because its using get_stylesheet_directory_uri() instead of get_template_directory_uri(). Can you look into this?
I made a quickfix by copying the cache-nsp folder to the childtheme directory, but wait for your reaction before I really start modifying NSP myself.
Kind regards, Sjef.
