wodrpress Help: always ask ftp access after I moved to a new server

Guys, yesterday I moved my WP to my new server,

I copy past all WP files, and I created a new db file and rename it as like my old one. and created a DB user same like old one with same privileges. and my blog works fine.

in admin section,

-when I click upgrade to 2.8.1 link,
-when I tried to update my plugins,
- when I tried to upload an image to my post,
Its open a new page to ask my ftp access.

why is this?
I changed my wordpress folders permissions as like my old one.

am I want to put the DB surfix _WP ???
how?

or any other advices?
what is my mistake?

thanks in advance

 

Try to add ftp access & upgrade, I have done this before & got no prob. If you have more problem than contact us.

 

I added my ftp details,
but it asks again and again for every single work.

 

Than there is somewhere you have done a mistake while transferring your files. It's a serious Problem. Contact me with your IM. I have to check it to help you.

 

I save my ftp info with my firefox browser, then I dont have to keep putting the info in. I didn't know WP would save this info for you. Even in 2.8 I have never seen such feature.
