We have one product page on our website that will randomly started displaying an error when you try to open it. It displays perfectly in the search results, but when you try to go to the actual page, it won't display. The gist of the error is that we do not have authorization to access this page.
The issue will eventually resolve itself after several hours, but if we try to fix it, the only method we've found that works is placing it in a new category and removing it. It's a popular item, so we would rather not wait for it to resolve itself, as it does this almost daily.
Any suggestions on what might be causing this issue and how we can prevent it?
