I'm getting an unknown server tag error. I have .net 4.0 on my local host and it works fine, but on my webhost they have 2.0

 

 I have:

 at the top of the page and

 

 <dotnetgallery:gallerybrowser runat="server" id="GalleryBrowser1" Width="675" Height="430" />

 

In the page.

 

I have the dll in the BIN folder. It works fine on my local host, but not when I push the files to my webhost.

 

Any help? Thanks.
