For some reason when creating a custom ribbon action with Visual studio it seems that no matter what you do, the ribbon button or action are never updated.
The Solution that worked for me is
1) retract the solution
2) delete the feature from the Visual studio project
3) Create a new feature in the visual studio project and add the custom ribbon action
4) deploy the new feature.

I had a custom web part that is running code that required elevated privileges and was running within SPSecurity.runWithElevatedPrivileges as below
SPSecurity.RunWithElevatedPrivileges(delegate()
{
SPSite siteColl = SPContext.Current.Site;
….
}
I kept throwing an access denied error.
after some investigation I found the solution at this useful blog.
the problem in short is, I was using a reference to the SPSite obtained from the SPContext. This reference to SPSite was created before the code entered the RunWithElevatedPrivileges block. Therefore, the reference to the SPSite was running under the current user privileges even though it was placed within the RunWithElevatedPrivileges block.
The solution is to obtain a new reference to the SPSite created within the RunWithElevatedPrivileges block as shown below.
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite siteColl = new SPSite(SPContext.Current.Site.ID))
….
}
