AJAX IMAGE Swapper support thread

[cocteau]

Thanks for Jay and the others in this thread.
All your comments help me pass through tons of problems and finally get the mod run.
I am a total newbie on site building and know zero about html css php sql things..... (thanks for ZC, I learn a bit more now!)

After over 20 times 1.38a fresh install and reinstall on 6 different public host. I finally get the AJAX mod run.
On this stage I just need ONE function by AJAX is, when I change an attribute, a related image replace the main image.
Here is my success test site:
http://cocteau.xtreemhost.com/index....roducts_id=193

Then I made a full back from this server and database and hv a formal transfer to my live server. AJAX refuse to work again

I use the Firefox Web Developer plugin try to view what's wrong. I got 2 error when load the page. (thanks for this great plugin too it really help me a lot a lot a lot...)

When I try to access the admin>AIS manager (V3.14), I get the well-know "please select a category first" problem. Error Console show this error:
(elements not find)
/admin/AJAX servers/AJAX image swapper server.php?action=loadProducts&category id=68&id=1236952311532

When I try to load my test page on the live server, another well-known "Spinning Pie" on there.
http://paper-tee.com/online/index.ph...roducts_id=193
Console show this error:
(elements not find)
/admin/AJAX servers/AJAX image swapper server.php?action=loadImages&products id=193&options id=1&options values id=29&id=1236952381618


I am quite sure this was caused by my server spec. or wrong settings. And AJAX is quite a server sensitive mod maybe.
Please see the brief of my Server info:

Server OS: Linux 2.6.18-92.1.18.el5
Database: MySQL 5.0.45
HTTP Server: Apache/2.2.3 (CentOS)
PHP Version: 5.1.6 (Zend: 2.1.0)
PHP Memory Limit: 16M
PHP Safe Mode: Off
PHP File Uploads: On

Any suggestions or direct helping may pull me out of this two week long nightmare...

PS. and sorry for my poor English also
