Your first error seems to be the same problem as here:
viewtopic.php?f=35&t=31912

Check your SysConfig here:
Ticket -> Frontend::Agent::TicketOverview

and reset the entries.

Upgrade the installed addons via command line (otrs.Console.pl) first... There were some changes in the directory/file layout of OTRS.

Install the most recent addons solved the problem.
