Lee, is normal. I explained to you where is the prob few posts above.
Get on my board for the fix, if you really really want to use access masks (it will add another query). :)

I did try what I thought would account for access masks but it didn't work, probablt the code I used was wrong. I'll take a look at TW.com now, thanks for the info TECK :)

How is having access masks off on a forum even feasible for most people? I have a admin/mod forum, if I turn access masks off, non admins/mods can view the board.

Set perms individually for each forum. A little longer in the procedure but it will save you a precious query.

Heh, I didn't know also. Chen was kind to show me a trick, is pretty complex (at least for me) :D

I have to agree the permissions is one of the harder things to accomplish ;)

Have you got a link for the code as I couldn't find it at TW.com.

I will post it in there later on after I test it properly... :)

Slick hack, but I'd prefer a LINK ~~ rather than assuming each user wants to "view similar threads" every showthread.php page view.

Also, it seems like this hack is a LOT of work just to duplicate functionality that's already built into search.php
(select a subforum // search in titles only )

In showthread.php, you might want (need) to check $searchenabled and $cansearch values
and conditionally null the template if search isn't currently enabled...

but piping it to search.php would take care of:
-- PARENT/sibling title searches
-- permissions
-- runs the title text through BADWORDS

In other words, I'm suggesting that you try this approach:

Create a link to search.php (essentially, a submit button)
& pass post['title'] and forumid as hidden fields
(user sees nothing other than a button, or link, labeled "find similar threads")

That sounds interesting. Could you come up with something like that?

What are the minimum PHP version and MySQL version requirements for this hack to run? Does it still require PHP 4.1 or will it run on 4.0.6?
