Just installed a Payment module provided by CardSave. It appears to be based on the CEON payment module.
I'm getting a warning message on the homepage saying:
Warning: You do NOT have PEAR:Crypt_Blowfish installed on your server!
Now, I've tried a few things to resolve this but ultimately I'm out of my comfort zone (PHP/MySQL) and this appears to be more about server configuration.
I've tried making a custom php.ini file which includes the path to Pear. I've installed Pear in my home directory and set the include path to that. I've installed Blowfish into my Pear directory.
But I'm still being given the same warning message.
