What is wrong? Can you please help my?

Many thanks

what did you change on the code?

[majo053]

Basically anything. I only commented ticket lock code. This is production server and on my devel server this error messages I not see.

This is files that I changed:

Kernel/Output/HTML/Standard/AgentTicketEmail.dtl
Kernel/Output/HTML/Standard/AgentTicketActionCommon.dtl
AgentDashboardTicketGeneric.dtl
AgentTicketActionCommon.dtl
AgentTicketEmail.dtl
AgentTicketEmail.pm
AgentTicketPhone.dtl
AgentTicketSearch.pm
Article.pm
CustomerLogin.dtl


My Apache error log:

[Tue Nov 29 20:05:39 2011] -e: Use of uninitialized value $Param{"Total"} in numeric gt (>) at /opt/otrs//Kernel/Output/HTML/LayoutTicket.pm line 1216.
[Tue Nov 29 20:05:39 2011] -e: Use of uninitialized value $Param{"Total"} in division (/) at /opt/otrs//Kernel/Output/HTML/LayoutTicket.pm line 1217.


Is this "Need valid SortBy" a big problem?

[jojo]

yes, this will be an issue. plaese revert your changes and try again

[majo053]

Revert which file?

[jojo]

the files you changed

[majo053]

Hmm...doesn't work Can you help me please?

[jojo]

as OTRS does not throw these kinds of errors some of your changes would be the cause...

revert all changes you did, delete the caches and restart apache
