Maddening problem: Rewrite does not change directory

This has been driving me absolutely crazy.

OK, this might be difficult to explain:

I have a gallery on my site which uses a heavily modified version of minimalgallery. It was working fine for a long time, and then I think I must have made a change to my htaccess file and can no longer get things to work correctly.

The gallery just parses the directory and displays any sub dirs and links

The problem is that while the gallery will load the default directory, clicking any link does nothing. The URL shown in the address bar is correct-- but it won't actually change directories.

Any ideas?

If what I described doesn't make any sense, PM me and I will send the URL and you can see for yourself.. like I said this is driving me absolutely crazy for a year now.

You'll likely need to post some example URLs (with no real URLs) and some relevant htaccess codes.

Just visiting the actual URL won't help (and really isn't necessary).

I've taken everything out of htaccess right now because it wasn't doing anything.. but I will post some of the old ones

Here is the truncated default url: .com/mp3/index.php?mg_cat=cloak

If I click a link to change dirs .com/mp3/index.php?mg_cat=LPE

The address changes.. but the browser still just shows the default

RewriteRule ^mp3/sttm /mp3/index.php?mg_cat=Slaves_To_The_Metropolis [L]
RewriteRule ^mp3/cloak /mp3/index.php?mg_cat=Cloak [L]

Those are some of the old rewrite rules I had in an old htaccess from when (I presume things were still working)
