Authorize.net Phasing Out MD5 transHash

Hello,

You will need to provide a step by step process with all details like which kind of user account do you use, which product, which payment methods etc etc...

Because we make some tests on your website, and it seems that everything works well, see my screenshot :

Hello,

You use an 2.6.4 HikaShop version with a more recent plugin, and so this kind of issue isn't really a surprise.
From this several solution for you :
- Update your HikaShop
- Don't use such recent payment plugin.

Sorry for this return.
Regards

In the file authorize_end.php of the plugin, change the line:
hikaInput::get()->set('noform',1);
to:
JRequest::setVar('noform',1);
and in the file authorize.php of the plugin, change the line:
$value = hikaInput::get()->getString($key);
to:
$value = JRequest::getVar($key);
Note that you might have other issues using the plugin as this version of the plugin was made for HikaShop 4.x and recent versions of Joomla.
