[PROBLEM] Error 500 after new istallation

[Tim Curtis]

could it be a to weak power supply?

Try

- Menu, Configure, System
- Menu, System info

In the System Parameters section look for lines like below. Typically if the Pi draws more power than the supply can provide, some sort of "Undervoltage has occurred..." message will show up after "Throttled text"

Code:

Throttled bitmask = 0x0
Throttled text = No throttling has occurred
