No login area after 18.0 upgrade via OCC

NC version: 18.0
Linux (custom 2.6 kernel)
Apache: not sure-- running on a web host, Cpanel 84…0.21
PHP version: 7.3

After upgrading to NC 18.0, I am faced with a blank nextcloud screen with no login option box/area as can be seen at https://ibb.co/746VWH0

Is this the first time you’ve seen this error? Y:

In your logs, there is only a last massage of a successful update. Is there perhaps more in the webserver log? Also consider using the developer mode of your browser and check if some resources fail to load.
