After migrating to version 16.0.6 the Apps screen goes blank with no info

After migrating to version 16.0.6, which went well, I noticed that when I click on the + Apps menu the screen goes white with only the headers.
Any recommendations or clue?
Thank you.

I restarted Apache and did not resolve it.
I rebooted the server and it also did not work.
But when I logged out and logged in from my admin user the problem was SOLVED.

This is a already known minor issue which can easily been solved. See:

BTW, the search function in the upper right corner of this forum exists, to check if an issue has already been reported/answered/fixed to reduce multiple appearances :wink:
