Hey Caroline,
I’ve investigated the issue, it was caused by an is_product() function in the theme’s “functions.php” file – in one place the function was being used without checking whether the WooCommerce plugin, which supports it, is indeed installed on the particular WordPress instance – which messed up the posts created automatically by the FeedWordPress plugin. I’ve corrected the file, and will also include this fix into the next update of the Shogun theme. My apologies for the inconvenience, and thank you for reporting this!
Sincerely,
Andrii / Satori Studio
