wp_get_current_user is overridden

Hello,

We have an issue when calling wp_get_current_user().

This is the issue we’ve seen:

Naturally we’ve contacted YoastSEO and asked for their help. They have identified that the source of the issue lies with your plugin.

Here is what Yoast said:
We have brought this issue to the attention of our developers, who have identified the problem in the code of the Plugin Load Filter. The respective plugin authors will need to fix this issue. Specifically, Line 73 should be modified to something like return WP_User( 0 ); . The Plugin Load Filter is currently overriding wp_get_current_user , which is acceptable, but it fails to maintain the expected return type of be WP_User . It should always return WP_User, not an integer int .

Can you please help resolve this issue?

Thank you
