Paragraph and Single Word Translation

I updated to Safari 10 and my Paragraph and Single Word Translation is not working

The paragraph and single word translation in Read&Write for Mac uses Flash, for the Sierra update Flash is disabled.

To enable Flash so the translation works please do the following:

1 Open Safari and at the top of the window click on Safari and select Preferences.

2  Click on the Security Tab and select Plug-in Settings as in the picture below

Safari Security window

3. You should now see a window that looks something like the one below.

Safari allow websites window

4. Change ‘’ ( or '’)  to ‘On'.

5. Now select Done
