I've been using SMF for quite a while now, and I do love it very much. There have been a couple of hiccups along the way, but nothing this big. I'm using SMF 2.0.
Okay, so this is what happened: I deleted two posts from smf_messages in phpmyadmin. Both messages were from the same topic, and now that particular topic doesn't show up at all in the board it should be in. I checked the mysql tables, it does exist and it's linked with the board it should show up in, it just doesn't. Also, I can access it just fine if I type in the URL.
So the topic was showing up just fine before I deleted the last two rows from smf_messages, and after that it just disappeared.
If you need any more info, please say so. If anyone could help me figure this out, it would be greatly appreciated.
