I've been in contact with EPay regarding the EPay payment plugin. I want to change the language in the payment popup window, and were told to change a setting in file \administrator\components\com_hikashop\extensions\plg_hikashoppayment_epay\epay.php
Add the following at line 99:
"language" => 4,
just above "instantcallback" => 1,
I followed the instruction, but the language is still Danish. EPay then sent me the following email:
"I've tried to make it work. Everything is done right, but it's like Hikashop is ignoring the changes. Maybe by using some kind of caching. Unfortunately, I was unable to find how to clear the cache. Can you try to contact Hikashop about this?"
Any suggestions?
