Errors after update to 5.0.1

[coolmf]

Hi

Ran update from v4.11 to v5.0.1 with no other problem than Module FAQ.pm not in @INC
So i downloaded FAQ-5.0.1.opm and updated that.
No errors in logfiles, everything looked ok.
Created new danish notifications and deleted the old ones from v4.11
Now all of a sudden i start getting errors in /var/log/httpd/error_log

and this In Admin --> systemlog:

Mon Nov 2 14:47:13 2015 error OTRS-CGI-10 Could not update To field for Article: 3992.

I also noticed that the emails is missing the body content <OTRS_CUSTOMER_Body[30]>

[coolmf]

Ok, more problems.
Now im not getting emails when customers create a new ticket.


Edit:
i recieve mails when they update a ticket.

[coolmf]

Update:

Fixed the problem with missing body in emails.
Changed <OTRS_CUSTOMER_Body[30]> to <OTRS_CUSTOMER_BODY[30]> in all my notifikations and it seems to work.

Now i upgrated to 5.0.2 and it still works with <OTRS_CUSTOMER_BODY[30]>

I also fixed the problem where it didnt send mails to me about new tickets.
Personal settings --> Ticket Notifications --> Ticket create notification was suddenly unchecked.

But also discovered a new problem: when a customer replies to a ticket i get Ticket follow-up notification (Locked) even if the ticket has status as open
