I would like to setup the redirect hook so that when the users log in, they will be directly taken to the page that they just tried to access.
When I try to access a private page as a logged out user I get URL
http://svn.amebylon.net/?my_redir_to=%2Factivity
but once I log in I am taken to the home page instead of the activity page. Listed below is my config file. Please let me know what should be corrected to make this work. Thanks!
