Is this the case? Will I need to modify these php.ini files to be able to use a long zip code list with your extension (for NY, that is probably the case).. . . Use as many rows as you need, mine had about 400.
However, there is a one line addition to two different php.ini file to enable OC to use that many rows.
The details are listed in the installation instructions. It will take seconds to make the modification.
Where would I find these two php.ini files? I'm assuming these are on my host, and not OC files?
Would I have to make sure my host company lets me do that?
