Check this website which i created in a demo site:- http://myseat.byethost14.com/pos/
User Id:- test

Where select a store and input in warehouse or add client area then you face this error:- "Unknown column ‘zipcode’ in ‘field list’
For this error i tried this thing:- Login in FTP and Go to Includes/update.php edit that file and on top 5th line you will find 2.1 , please change that to 2.2 also on line 22 change 2.1 to 2.2 and run your script again.
But after changed the figure i got this:- Duplicate column name ‘zipcode. Please anyone help me to solve this issue.
