After upgrading SuiteCRM and logging out I could not log back in because the login screen was blank.
I had upgraded from SuiteCRM-7.5.1 to 7.11.2 using the Upgrade Wizard and the files below.
I logged out and back in between upgrades. After the last upgrade the login screen would not load.

I was able to get it to load the login screen by using these commands (in my FreeNAS iocage jail [os=FreeBSD,httpd=apache24,php=7.3.3])
rmdir /usr/local/www/apache24/data/SuiteCRM/lib/SuiteCRM/Utility
ln -s /usr/local/www/apache24/data/SuiteCRM/lib/Utility /usr/local/www/apache24/data/SuiteCRM/lib/SuiteCRM/Utility
chown www /usr/local/www/apache24/data/SuiteCRM/lib/SuiteCRM/Utility
I am not sure if this should be a bug report and how to make such a report. This took me awhile to find and I hope my solution will help others.
I think my solution works but any suggestions for a better solution are appreciated.
