I tried to apply a Catalog Price rule but I received a "502 Bad Gateway" error message. When I returned in the Catalog Price Rules page/interface I deleted that rule but, after that, I had the "There are rules that have been changed but were not applied. Please, click Apply Rules in order to see immediate effect in the catalog." system message. It seems that rule is hanging in the queue so I can't apply any rules because the first rule in queue is that wrong.
How can I delete (from the database, I suppose) that wrong rule to apply?
Thans in advance.
