WP is not letting me add any more plugins – Help Please

Aanii and Good Morning to you all.

I am putting up a new WP blog and I am using the 2.0 I believe it is.

I have been adding plugins and widgets just fine. All of a sudden the plugins and widgets are not showing up after I Upload them to my server.

Is there a second page or something that I am missing?

I checked and the files are loading to my server fine.

Any and all help greatly appreciated. Thank you for your time.

Blessings
