[SOLVED] all my url's get itemid= instead of actual file names

I hope somebody can help me. I obviously did something but don't know what. Long story short, all my url's have itemid= instead of actual file names. They are all unique. I'm guessing it has something to do with url rewrite but don't know how to fix it. This is what I get when I try to configure it:

URL Rewrite Setup
Apache mod_rewrite

The Apache mod_rewrite module is installed on most Apache servers by default. If you are unsure of what method you should choose then select this. Gallery will try to detect if your server supports mod_rewrite.
PHP Path Info

Using Path Info is supported by most systems. With this method Gallery parses the URL itself during the request.

It is recomended that you don't activate the 'Download Item' URL since it will slow down Gallery.
Block hotlinking is not supported.

Up until 2 days ago everything was working properly. I hope this is enough information to solve the problem.

Gallery URL = http://lloydspitalnikphotos.com/main.php
Gallery version = 2.3 core 1.3.0
API = Core 7.54, Module 3.9, Theme 2.6, Embed 1.5

Webserver = Apache
Database = mysqli 5.5.24-percona-sure1-log, lock.system=flock

Rows in GalleryAccessSubscriberMap table = 6120

Thanks suprsidr. I set this up in 2008 and haven't had to deal with it. I don't remember any of this any more but I think it's in .htaccess. If I'm right I have no idea how to direct it to show actual file names in the url instead of itemid. Here is my .htaccess. I really hope you can help.
Thanks,

Thanks again for your help. I'm installing 2.3.2 and am hung up at step 8. I get this message: Warning: rmdir(/home/lloyd/www/www/g2data//cache/entity/) [function.rmdir]: Directory not empty in /home/lloyd/www/www/modules/core/classes/GalleryPlatform.class on line 516. I know I should know more than I do but I'm at at a total loss. Sorry to keep bothering you.
