Fresh install of latest version of EDocman, on Joomla 5.3.x with Yootheme Pagebuilder template. I've tried switching on & off: Load jQuery Library / Bootstrap version / UIKit.
But the "Submit" Button for Upload Documents is not appearing. Although the Cancel button next to it appears. Curiously, I can find where the Upload button is supposed to be showing, by hovering cursor over the space.
