If we upload images, the default Duration is: 10sec. But after we updated to cms 4.0.12 every layout is shown one Minute.Now have to set the duration on every Layout with images manually.
In CMS 4.0.12, the Default Duration is still set to 10 seconds.
To change this duration, navigate to your CMS install-root. Then, go to the modules folder and modify the images.xml file at line 34.
When you create a layout in Xibo, the total length of the layout is determined by the longest region.
Could you show your Layout Settings? That might be where the problem lies.
