No navigation buttons

Hello!

Great plugin, but I have one serious problem… there is no ANY navigation buttons in my slideshow. Of course, I’m experimenting with navigation settings, but it doesn’t matter. I see slideshow and it works, but there is no any navigation buttons on the screen.

Of course, I tried to deactivate all plugins. But it can’t help.

Thank you!
