'idSite=' is missing

I have a problem since I updated to 10.0.7 from latest 9.x release

WP-Piwik 0.10.0.7 is successfully connected to Piwik 2.13.1. You are running WordPress 4.2.2.

This appears in the tracking code window (I am using js/index.php).

<!-- a:2:{s:6:"result";s:5:"error";s:7:"message";s:52:"The parameter 'idSite=' is missing from the request.";} -->

Here is the result of the Support Test Script

Any ideas what can be the problem?
