Wp Super cache: old url reference when enabled it.

I moved my wordpress site to a new domain.such as new_domain.com from old_domain.com. I changed the database that should when moving domain(site url and home using phpMyadmin). my site works fine normally.
but, when i enable wp super cache. it points back to old_domain.com the css and other staffs.
so, page content loads but, not styles, images. themes!
what’s working with me. i can not figure out! Help me please.

i made sure that i cleaned the cache. uninstall the plugin. i checked the .htaccess there is no reference back.
still no clue.

More relevant info: i previously installed W3 Total Cache .tried some. but, then uninstantiated. I only moved the database, not the files.

is it a problem with APC, just something like this. i am on a shared hosting.

Strange! never faced such problem!
