Comment 8 for bug 1659620

Running Ubuntu 18.04 with openstack-dashboard 14.0.3-0ubuntu1~cloud0 and having issues with certain modals not working (create object container, create keypair, upload keypair, create server group) all popping up as blank modals. This has been a chronic issue for us for Ubuntu 16.04 and also 18.04 spanning multiple OpenStack releases but when we first upgraded to Rocky these issues were gone. We did not seem to have any issues with openstack-dashboard 14.0.2-0ubuntu4~cloud0 and this was very surprising to see however we recently upgraded to 14.0.3-0ubuntu1~cloud0 and we are now having these issues with broken modals again.

The problem seems to be related to what your memcached configuration is in /etc/openstack-dashboard/local_settings.py although I have not been able to pinpoint what exactly is the relationship between memcached and the collectstatic/compress operations building good or bad javascript.
