I notice some module has
admin folder
and include folder

is it the admin folder at the root
and include folder at the root

or is it admin folder within include
and include folder within include

or is it admin folder within include
and include folder at the root

Also in previous version of 1.3.9
it was administrator
now it is admin
but if i change the folder administrator to admin, my login link won't work

and I don't know why I got this error
1054 Unknown column 'p.products_carrot' in 'where clause'
in:
[select count(*) as total from zen_products p, zen_products_to_categories p2c where p.products_carrot = '0' and p.products_id = p2c.products_id and p2c.categories_id = '65']
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I am using ZenCart 1.3.9

Anyhelp would be appreciated
