404 underscore-min.map not found
In our adaptive forms we are using some jquery features and in 6.2 all is running well. After migrating to 6.3 we get an error:
Request-URL: http://localhost:8080/lc/etc/clientlibs/fd/af/I18N/underscore-min.map
404 underscore-min.map not found.
Any ideas what's going wrong?
