Possible bug?!

[Hoxxy]

I have had 3 members saying all they can see is "content visible to registered users only" in some of my posts, normally hitting edit and resaving sorts it, I think this may be a bug that need fixing,

ps, the members have all been regulers (not newbies).

this code mostly happens on boards with the hide hack installed, but here is no hide hack installed.. i know there is a hide link hack installed maybe this is causing the errors
