Hi,

Since modify last time, I meet another problem.
Although these original get error forums can access and post, but their prefix don't show on viewforum.php page.
Even some viewtopic.php page appears several prefixs, I ensure only set one prefix.

Example:

1. This is a normal [http://220.134.232.37/phpBB3/viewforum.php?f=14 ]forum and [http://220.134.232.37/phpBB3/viewtopic.php?f=14&t=414 ]post.
2. This is a [http://220.134.232.37/phpBB3/viewforum.php?f=15 ]forum without prefix and [http://220.134.232.37/phpBB3/viewtopic.php?f=15&t=415 ]post.
3. This is another [http://220.134.232.37/phpBB3/viewforum.php?f=16 ]forum without prefix and [http://220.134.232.37/phpBB3/viewtopic.php?f=16&t=398 ]post.
   p.s. The third post is without prefix originally, I edit it for test. The result appears several prefixs.

Some mods relate viewtopic and vewforum following:
