I bought this application thinking about saving time so I don't have to do it myself. In the end it did I was stuck with an error in the installation process for which the author did not give me any help, on the contrary he told me that it was my fault because he did not follow his instructions (that is not true). He told me that the problem was in my local server when(not true, again) I run several applications much larger and more complex than this application in the same server.
In the end he sent me to ask for help elsewhere, I am also a web developer so I am going to make my own application. I did not lose much, only $ 12 but a lot of time that was what I was trying to save.
