In theory, you should never need to manually flush the cache. In practice, it has been useful under various configurations in the past where Role Scoper failed to auto-flush the cache appropriately. In theory, those bugs are all fixed now.

As always, the manual "flush cache" is useful in answering your final question - "Could it be something with the cache?" If and when you discover that it is, I will be disappointed but glad for the feedback.

Regarding the user who can edit unless you assign him the editor role for a category, my first thought is that he can already edit it due to some other role assignment, and that something about the category role assignment is triggering a db/php error. Yes, in theory it could be related to a corrupted cache, but I don't have any specific experience or suspicions regarding this issue.

This in the rare class of bugs that (for the sake of sanity and morale) I probably can't/won't pursue until I can log into as the symptomatic user and generate some diagnostic output. E-mail me through the contact form if you'd like to go that route.

Dare I ask what the other weird examples are? Oh, and what RS version are you running?

FYI I've disabled caching after reading through other people's posts in this forum, as we have more than 40 people contributing to our site and the consensus seems to be that having many writers can cause issues with the cache feature …. is that a correct assumption on my part?

Actually, you're in a better position to answer that since my testing setup is not adept at simulating multiple concurrent users. I have added a significant bit of precautionary code since the last (and only) WSOD report that stemmed from a cache corruption. At least one other site with dozens of authors was running with the cache, last I knew (Daisy - can you confirm and/or offer any reports on recent results?).

I did correct one cache storage bug as recently as rc9.9227, but I'm not aware of any other issues, nor have heard any suspicious reports.

Turned out that somehow, one of the user's posts wound up in the "Restricted" list — it wasn't assigned as such. As long as that one post was "Restricted", the user couldn't edit any of his other articles.

Can you reproduce that by temporarily restricting the one post again? I haven't been able to.

Issue hasn't occurred since, and it does seem possible that the issue occured after I did a bulk restrictions edit.

where is rc9.9227 ? is it available for download yet?

Thanks Kevin!

FYI I'm running RoleScoper on a production site with about 45 contributors who are writing daily, and often concurrently - BaseballDigest.com. Other than the few minor issues I've encountered, it seems to be doing what it's supposed to do. Not sure how many other sites using RS have that many contributors — I saw at least one with contributors in the hundreds — but if there's anything I can do to help in the way of testing, feedback, etc., let me know.(And yes a donation is on the way.)

Thanks again.
