BUG? I upgraded my trial license and my vertical menu lost it’s application tab icons for active tab & inactive tab. Has anyone experienced this?

UPDATE: I reset all of my active and inactive tab icons and a few hours later rebooted my server (maintenance), and I LOST THE ICONS AGAIN! NOT HAPPY! I have over 150 menu items.

Yes it’s a BUG!

First get rid of all your cookies, cache etc. Then restart and try again.

Done that a few times and it happened again.
