We've been running into this problem with Version 4.7.22 (current) of the cloud system for a week or so. It is showing itself in a 4500+ page thread (and no, that's not a typo). Sometimes the posts come back, sometimes (we suspect) they do not. Given that the self-hosted version experienced this same problem at the same time we experienced it, and that required a patch, it doesn't seem like clearing our cache will do much good. Is there a patch coming for the cloud based system? Steve
