On occasion I will receive an email notification for a conversation I'm not in or part of. Other members have mentioned this as well.
I appreciate your help.Hmm, none of those addons should cause anything like that. Beyond that, I am not sure what it could be. Without being to replicate it on demand its almost impossible to debug.
That's what I was suspecting, and I'm pretty sure it's been occurring for several years as part of the vBullitin migration.Based on your posts, it sounds like there is some database corruption.
If you're not sure how to resolve it, you will need the services of a third party.
