If you got a blank page with the word “Done” (or similar) after activation, then your browser timed out waiting for Wassup to finish upgrading its tables. This can happen if your database is very large and your server is very slow or very busy. Don’t worry. Your site is still running and your admin area is still accessible.
Try enter your “admin” url directly in your browser location bar: ex:
www.mywebsite.com/wp-admin/plugins.php.
and you will see the list of plugins with Wassup activated. Since a few days has passed since you posted this, you may also be prompted for login.
If you can’t access your admin area even with the direct URL. Then you have to remove “wassup” folder from wordpress’ plugins folder. You can do this by logging into your host server account and use the “File Manager” in your host C-panel.
Good luck.
