Update, Error 500

Hi

I was trying to update Hikashop from 1.5 to 1.6, but was unsuccessfull.
The error message was this one:

---

500 - An error has occurred.
JDatabaseMySQL::query: 1060 - Duplicate column name 'taxation_cumulative' SQL=ALTER IGNORE TABLE `jos_hikashop_taxation` ADD `taxation_cumulative` TINYINT NULL;

---

Any hints what and where should I change to make Hikashop run again?
Thanks

Hi,

You should turn off the debug mode of the joomla configuration and try again.

Thanks. Soooo easy... )))
