Hi,
if the business owner claimed the listing as a subscriber and you don’t change its role, there is no way for him to edit the reviews.
If you leave an option to business ownser to moderate the reviews of their own listings, negative reviews or comments would never get published.
Only if you change the business owner role to author or above they’ll be able to edit reviews of their listings from the back end and that looks like a bug as well, because they can do it even if the wp-admin is restricted.
I’ll ask to the developers to verify.
Please avoid opening topics with title like “reviews” (as you can see there are already 7 with that title and that doesn’t help us with keeping our forum efficient). Please always briefly describe your problem in the title.
Thanks
