I have an error 500 when I tried to add a new ticket after upgrade from 1.2.0 to 1.4.1 :(

Hi, I have finally upgraded my Redmine from 1.2 to 1.4.1 with a big help from the Site5 support however now that I can see in the admin that I have version 1.4.1 I have the same error when I try to open a new ticket, or chech activity or chech document page... any idea ? thanks...

Here is the log info for adding a new ticket for example :
