The problem is that the special prices are showing in case they are actually filled for a specific product. The dates are set correctly, meaning the date on which is tested is outside the period that should activate the special price. Caches have been cleared, index reindexed (multiple times) etc etc. All without any positive result. A while ago the hosting company activated HHVM on the server but due to several problems this was deactivated a couple of weeks back. Could this still have some effect on the special prices still showing? Or should I look in a entirely different direction?
