Found this: https://central.owncloud.org/t/owncloud-login-button-wont-work-and-files-after-login-wont-shows-up-also/1707; deleting the "disabled="disabled"" code lets me in but, as the original poster, no files (and no menu is working). Also found two other topics but, as a new user, I'm only allowed to post one.
My server is at home, no VPS, no cloudfare, etc. Everything was working fine with Owncloud 7 packages.
