I did run the upgrades and the only issue was when it attempted to copy the files into the thumbs folder. I modified permissions on a single folder, refreshed the page, and everything went fine.
I have no issues displaying reviews.
Also, I FULLY understand the risk of allow HTML in reviews.
My goal is NOT to allow HTML in reviews, I assumed this would be obvious.
I had hopped there would be a simple way to remove these html characters since they only appeared after my upgrade today, and they make reading the reviews very difficult for the users.
