I see something odd when I upgraded from 7.5.3 to 7.5.4.1.
I closed the board performed the upgrade.
After it was complete it prompted me to open the board. It did not work. In fact I got a blank page when I selected submit.
Going to control panel >>Home did not open the board, still a blank page after submitting.
The only way to open the board was to goto Control Panel � Primary Settings and deselect "Close Board?"
I checked the permission settings in the control panel and all show okay.
