I was browsing my forums, and I noticed that some topics numbers were missing. For example viewtopic.php?t=2 - viewtopic.php?t=8 exists, but viewtopic.php?t=9 doesn't. The topic used to exist but was deleted. So now it just skips #9 and goes to viewtopic.php?t=10. My question is how do I change the topics number so they are re-ordered correctly? I want it so viewtopic.php?t=10 is now viewtopic.php?t=9. But I looked in my database and have found quite a few topics have been deleted. Is there sql I could run or a modification I could install? I found one for changing the user id, but I couldn't find one for what I wanted to do.
