Sharepoint 2013 Designer workflow issue "Server-side activities have been updated

Apr 5, 2016 at 12:53 PM
After installing this SPD repeatedly told me "Server-side activities have been updated" and would not let me create a new workflow. I restarted designer and the server multiple times with no success.

The solution was to clear the designer cache by deleting all files in the following locations;

%USERPROFILE%\AppData\Local\Microsoft\WebsiteCache
%APPDATA%\Microsoft\Web Server Extensions\Cache

hope this is helpful for someone!
