iOS can't load data from javascipt

Hello!!!!

I have an aplication wich is a device that send data from a sensor to a webpage, it's working well but I can´t read the data from iOS devices. From Windows and Android devices it´s OK, but when I load the page from Safari for exemple I get just blank spaces.

I already check if Javascrit was available in settings page, but it still doesn't work.

Someone could give me some light?

Thanks a lot.
