mistery: posts disappear

[Baitona]

Hi all

i had a problem in 367, suddenly it came to my attention many complains from members,
their posts dis disappear,sometimes, not all of the posts,
but now and then one or two post of theirs will disappear,

i don't participate alot in the forum my self,
so i didn't see any thing my self, how ever other moderators started to mention the same problem

i have upgraded to 368, hoping to solve this mister, but still some mebers still complain about this also few moderators,

any suggestion please?

i have few plugins and products installed, but nothing to delete posts etc.

any help will be appreciated

regards
