Superspeed help needed in supercharging ATA

I heard so much success stories with the supercharge, and seems simple enough to implement, but when I use the template (also the newer 1.4 v) the static text dissapearred and posts in a certain category is not shown anywhere but in the homepage. Basically when I use the template, all I got is blank.
First I thought it was the effect of other plugins (renamed them one-by-one), not helping.

currently custom_query of a page looks like this:cat=4&post_status=publish&posts_per_page=5
Does anyone knows what's happening? This is the last step of finishing my site, everything else is finished, so your help is greatly appreciated. Many thanks in advance.

Site is:

(as a temporary solution I might put all to default template, however, supercharging my ata is actually really esssential to the site)
