Re: VBS and HTTP
I tested and Smarty eval works in my Tiki 12, 13, 14, and 15 test installs. I don't remember having to do anything to smarty to get them to work.
Maybe eval is disabled on your system? I found this:
https://doc.tiki.org/Requirements#Required_PHP_Functions
I found a closed problem about the smarty plugin and eval:
https://dev.tiki.org/item4527
I find /smarty/libs/plugins/function.eval.php in my test Tiki 2 through Tiki 7, but not in any of the others. Maybe that isn't the file smarty uses for eval anymore?
Sorry it isn't working for you.
