I just loaded the latest version 2.2.9.139 and got the error500 on the apps page..
I did a "soft reset", unplugged the box for a few minutes and restored to older version.. same thing...
any ideas on what to do ?
According to Release 2.2.9 available - #13 by bravenel this issue was fixed in 9.139 but in my case it appears to have caused it...
