When using ui.bootstrap in an angular project, I find a lot of errors like this: 'Template for directive 'modalBackdrop' must have exactly one root element. template/modal/backdrop.html'
I searched the entire internet, don't know why more and more people don't have them.
Search in the "ui-bootstrap-tpls-x.min.js" file for "/backdrop.html" (or whatever file is throwing the error). You will see that they end with a ' \n'. Remove that, and the error will be gone!
