I have your plugin installed along with Contact Form 7 and Event Manager – the site is quite large, about 1000 pages and posts.
Although the slider is working on the pages I have it on, in the WordPress wp-admin, when I roll over the left navigation “Captain slider” it shows the Contact Form 7 sub menu.
When I disable any of the three plugins, it works just fine. I’m wondering if WordPress has updated hooks for creating the menu and it needs to be tweaked in your plugin?
