slide show not working

I am using wordpress Version 2.3.2. I have two more sites for which i am using ver 2.3, now my problem is that my slide show is not working with this new ver 2.3.2 but its worked good with 2.3.

https://www.silde.com is site where we can make a slide and then after making they give a code like this [slideshow id=1657324662874477012&w=426&h=320]
i put this code in new post and slide show works, but with new version it shows only code not the slide show.

Please help me!
