[Plugin: Shortcode Exec PHP] Can't "save" or "test"

Hey guys,

I was able to save and test the code with a normal theme but when I installed a new theme yesterday, the plugin doesn’t seem to support that theme.

When I type the code in “shortcode exec php” and click “test” and “save”, it just doesn’t no anything, no reaction.

Here is the simple code I want to use:
name = click_id
Enabled = On
Output echoed = On
Line1 = return $_GET[‘click_id’];

I’m just wondering if I could manually insert the code somewhere in the template please? And how?

Thanks very much!
