Open Source Point of Sale
After creating, database, loading the files on server and configuring the database.php and config.php with my own, I,have the error :
Unable to load the requested language file: language/English/common lang.php
If you have selected a different language from english, you should probably get that error.
Please apply the language pack (https://sourceforge.net/p/opensourcepos/patches/16/) to solve it.
