I'm back after a bit of a break and nothing's been done to my site for a while.
I've added a new image and added a few hotspots to the image, however the resulting popup is now beneath the image.
Other instances of the module are still functioning correctly showing the module above the image as it should.
I have done nothing different with this new instance. In fact, I standardized the layouts so all images/maps interactions appear the same.
I have the latest version of MapMaker that you kindly upgraded for use with DNN 9.
Any ideas as to why, suddenly, there's this problem?
