Hope this answer is as easy as it sounds... When an error message pops up in the red box (of doom ).. where is the file that contains this error message text? I'd like to customize the wording for some errors. Can't seem to locate it in the language files. Thanks!
By the way, I am specifically looking to change the error message that appears when a trial subscription has already been purchased: "You signed-up for this trial subscription already - please return back to signup page and choose another product"
