I am been using browser_mod pop up for vacuum control on a tablet showing floorplan. It has been working flawlessly but all of the sudden the “start-button” is no longer showing at the bottom of the pop-up window. Any idea how to fix this?
I tested your config and I get the ‘Start’ button fine. Are you sure you don’t have a custom element that is adjusting theming or dialogs, even perhaps related to more-info?
Just to double check I have set my popup from a picture element like in your code, but I can’t reproduce. The fact that you have the border above where the buttons should be shows that they are likely there in the HTML but something is causing them to not show, which has me still thinking there is some theme element happening. As it is happening on a desktop, take a look at developer console and see what is included in the area where the buttons should show.
Themeing can stay around sometimes, so maybe try refreshing caches.
As it started happening recently, have a think about what you changed and that may help isolated.
