[Plugin: Nextgen Gallery] Slideshow won’t work

I’m trying to get the Nextgen Gallery slideshow to work. The thumbnails work fine. I’m using Nextgen Gallery 0.99.1 and WordPress 2.6.3. My provider is WebHost4Life. The URL for the site is https://www.holisticalternatives.net. I’ve tried it in Safari, IE7 and Firefox 3.0.3. Nothing works.

The following are my server settings:

* Operating System : Linux
* Server : Apache/2.2.3 (CentOS)
* Memory usage : 10.93 MByte
* MYSQL Version : 5.0.27
* SQL Mode : Not set
* PHP Version : 5.2.6
* PHP Safe Mode : Off
* PHP Allow URL fopen : On
* PHP Memory Limit : 32M
* PHP Max Upload Size : 2M
* PHP Max Post Size : 8M
* PHP Max Script Execute Time : 30s
* PHP Exif support : Yes ( V1.4 )
* PHP IPTC support : Yes
* PHP XML support : Yes

GD support

* GD Version : bundled (2.0.34 compatible)
* FreeType Support : Yes
* FreeType Linkage : with freetype
* T1Lib Support : No
* GIF Read Support : Yes
* GIF Create Support : Yes
* JPG Support : Yes
* PNG Support : Yes
* WBMP Support : Yes
* XPM Support : No
* XBM Support : Yes
* JIS-mapped Japanese Font Support : No

I’ve tried everything I can find in the forum to try and fix it. I’ve reloaded from scratch twice. I’ve set gallery permission at 777. I’ve tried various permission settings on the plugin itself (755, 766, 777). It just can’t be made to work.

Any suggestions?
