Importat first: The plugin basically works with 3.5.2.
(1) Date-picker don't work
It includes only Stings like "Juli/TT/JJ 00:00" which don't have any effect and will be deleted after saving. Unfortunatly I cannot manually insert datetime for start/end.
(2) Overview is broken sometimes
When I manage and save options for a single banner, it disapears and come back with page reload.
That's all for now. I would consider buying the new WPX Bannerize Plugin, but there is no price indication without installing the overall plugin which I refuse to do at the moment.
Having said that, it is still a very googd and functional plugin.
