Error get_page_permastruct

I’m getting the same error of this post – i.e. get the error: “Call to a member function get_extra_permastruct() on null” when Activate the Status of LightStart. After pressing the F5 key everything is okay, and the plugin seems to be working.

I don’t have the plugin WP Super Cache, so I can’t apply the same solution of the other post.

The error I get, with all plugins disabled except LightStart and WP Debugging disabled is:
