Powerstore 4.01 update to 4.5 admin error
We updated the powerstore per the instructions provided. The admin/settings area
now offers the updated choice changes for currency but, when selected the store does not change currency?
The following has not changed:
1) Shipping settings have not updated ( meaning the new updated choices are not available under settings )
2) admin Taxes have not updated ( meaning the new updated choices are not available under settings )
** Recieved this error when trying to update Mysql db.
ALTERTABLE ps4_products ADD ProductNonTaxable int( 1) ;
#1060 - Duplicate column name 'ProductNonTaxable'
Why would this occur?
