Redmine

I have downloaded last version of Bitnami linux stack and I have transferred all data from previous server to this one. Everythings are ok. Thanks for all.

I have a problem that I can't understand the reason. "Issue List Default Coulumns" on the Settings Page is ReadOnly!,
Firstly, this row was not exist in the Setting table. I have added it and I can manage this functionality by the manuel update of this row.
Problem still exist. I can't see related logs in the log file.

Yes, I can update some other settings..

Do you have any idea about this situation?
