Well I finally got around to fixing the stuff that was wrong. I had to ask shawnz from irc.msgplus.net/banana for help, and after he explained it to me, I learned one more thing about php error reporting. Now I fixed them, I also fixed another bug. I had comments/number working, but not comments/number/ . That little slash at the end caushed some problems, once again, that was fixed thanks to shawnz.

With fixing the / thing came another problem: the menu links no longer worked as intended.

I haven't fixed that yet, and that's next on my list of unimportant bug fixes. It shouldn't affect anyone unless they manually type a link right now anyway.

I want to get the comments posting thing working first, as right now all the posting is being done via phpmyadmin. Once that's done, I'll remove the database and do a fresh database install, because I need to change something in the tables for comments. The date and time of comments looks like crap.

<b>Edit:</b> Ohh yeah, and I need to re-add nl2br for admin posting because this is getting seriously annoying...

Edit2: Ohh yeah, turns out I won't need to do a fresh install, I just checked

I broke stuff when I changed the php version to 5, I changed some things in the admin panel, I tried switching back to 4, but that broke stuff in the admin panel. Now I'm back on php 5, and the only thing that's broken is the comments section.
<br /><br />
I've also done a few modifications for search engine friendly links, so comments are now dotlou.com/beta/comments/6 instead of dotlou.com/beta/comments.php?pid=6
<br /><br />
This doesn't seem like much, but it was loads harder than expected, and I'm glad irc.msgplus.net/banana exists, and it means that if google goes by here, things are going to be clear.
<br /><br />
There's a few little problems with the new url's though, but <i><b>most</b></i> of the problems are hidden to all of you, because it's for a feature I haven't released yet. This means that it won't affect the site just yet.
<br /><br />
All in all, comment showing is broken, comment posting isn't done yet, username and password changes aren't done yet in the admin panel, and comment editing/deleting in the admin panel needs to be modified a bit to work. This is taking loads more time than expected but I'm busy, so it's quite normal.

I'm trying to make everything work on php 5 now, and you'll notice the comments are working (or you would if that page wasn't causing me problems at the moment).
