I have deployed and then redeployed a .wsp on a Sharepoint 2010 server (the solution was developed on another 2010 server). The solution contains 2 web parts.
After retracting and removing the old solution, I added and deployed the same solution again, with no errors.
Afterwards, I deactivated and reactivated the feature installed through my .wsp file.
The problem is that whenever I try to add one of those 2 web parts to a page, I get an error saying "The operation could not be completed because the item was removed from the gallery".
Do you have any ideea what's happening? Anu help is greatly appreciated!
