I'm the developer of Captain Slider. I made it a couple years ago now and at the moment I do not plan on updating it any time soon. Why? It works. It still does what I intended it to do and still works for the majority of users. I personally don't have time to keep updating it as I provide it completely for free.
As with all slider plugins, there tends to be conflicts and problems a lot. Please read through the documentation. If that doesn't help, feel free to post a support thread here but I am not supporting the plugin at the moment so it will be up to other members of this forum to try and help you.
Sorry! Enjoy it anyway :)
