A WebPart on this Page cannot be displayed

I have a web part that I am trying to show up on the Central Admin Page and for some reason I get this:

Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type SiteCreateVisualWebPartSolution.VisualWebPart1.VisualWebPart1, SiteCreateVisualWebPartSolution, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5ca4be4793e0f56b could not be found or it is not registered as safe.

Show Error Details


I thought I added the webpart info to the Central Admin web.config file properly but maybe not.  Can somebody please provide for me how I should write the webpart into the web.config file?  Here is what I have put into the web.config file below:

<SafeControl Assmebly="SiteCreateVisualWebPartSolution.VisualWebPart1.VisualWebPart1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5ca4be4793e0f56b" Namespace="SiteCreateVisualWebPartSolution.VisualWebPart1.VisualWebPart1" TypeName="SiteCreateVisualWebPartSolution.VisualWebPart1.VisualWebPart1, SiteCreateVisualWebPartSolution" Safe="True" SafeAgainstScript="False"/>

What can I do to fix this issue where I am still getting problems?

Hi!

It looks like your safe control element is incorrect.
The TypeName parameter is incorrect - it should class name (without namespace, namespace is specified in separate attribute) or * is all classes from specified namespace are safe.
Besides it looks like your namespace include class name as well.

So try this:
<SafeControl Assmebly="SiteCreateVisualWebPartSolution.VisualWebPart1.VisualWebPart1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5ca4be4793e0f56b" Namespace="SiteCreateVisualWebPartSolution.VisualWebPart1" TypeName="VisualWebPart1" Safe="True" SafeAgainstScript="False"/>

Can you post code of webpart, so I check that namespace and class are correct? BTW check assembly name and publickeytoken (assembly name is name of dll file, without extension).

And you have a misprint is word Assembly in safecontrol element.

Sure, do you want to see the front end code or the back end code?  Which files would you like to see?  Thanks!
