It's been about 2 1 / 2 year that I have my website. But then I'll start using Security Role Fee. Currently I am using version 5.3.1 and all is well. About one month ago, I tested using the Paypal sandbox and the advanced security roles options of a person so that they can pay to get a Role by going through their profile. I read in the DNN 5.x book and it does not happen exactly as it is written, for example we can have only one Trial Period, because when you do the updates the boxes are being reset to empty. Well ok I can go without it and only use the Services Fee and Billing Period.
So I did test with Billing Period to a period of time (days) and as One-Time Fee and both worked very well. The problem there now is that I can not use the One-Time Fee since the user pays by Paypal and the transaction is completed when you click to return to the site with the result that the user paid but did not get the role for which he paid. Whoever, if he pays via Billing Period Example 1 Day, everything works like a charm, except that each day the poor user will have to pay again.
What I notice is that the choices Day or One-Time Fee, the way that Paypal does it during a transaction is a little different. Has Paypal  changed its way of doing things, ? As before the two choices worked fine, because the choice that I need is the One-Time Fee. Or do you know of a module that would do the job of the One-Time Fee especially if you have the opportunity to have a number of days that the role would last.
