hello everyone
version cb 3.1
after more research and more testing, I am able to do a redirect to the home page to connect, and solve the problem of blank page.
Just add two line in comprofiler.php
and more precisely in the body of the function confirm ().
The modefication is as follows
Remove the line:::: echo $ messagesToUser;
Replace with:
global $ mainframe;
$mainframe->redirect("index.php?option=com_acceuil&view=connect&Itemid=10",$messagesToUser);
you can redirect to the page that you prefer.
I am in your disposal for any question
