After update not working

What do you mean with “not working”? What’s not working? The plugin is active or cannot be activated?

YES https://s017.radikal.ru/i442/1408/bc/591a7bf0b561.jpg

Page Not found

???

The url shown in your browser is very strange: the access to the option page should not have an url like that.

Do you have any special plugin to change the admin side structure? Did you update from version 3.0.0 to version 3.0.3 or from a previous version (2.x)?

I have version 3.0.0 I just updated to version 3.0.2

give me please a link to download a previous version 3.0.0

I solved, thanks

Solved restoring version 3.0.0? Can you share how you solved so I can find the problem and avoid that issue to other users?

Thank you, Stefano.
