So I installed the module and enabled it. It said it was installed using the Mcrypt extension (I am on shared hosting with host monster) So I assumed the installed it on the server or w.e. I went to the settings and checked the create AES passwords box and set a path to store the key (I left the two key spots blank because I think it autogenerates these, right?) and Hit save. But when I try to use this with my UPS shipping module for Drupal Commerce it says AES is not installed, I understand if its a UPS module problem this isnt the place, but I just wanna know, did I do something wrong?
