When using the plugin AMR Shortcode Any Widget for Wordpress, placing a widget causes the screenshot display of "~tt" to appear at the bottom of the widget. I scanned the plugin and a theme from TT finding that TT does include code such as 'after_widget' => "</aside>~tt", suggesting pretty clearly that AMR somehow conjures this code to then display as text.
Now, I could ask the plugin developer to alter his plugin, however he has grounds to stand on with Wordpress basic compatibility requirements. So I'd like to ask ya'll at TT to see if there's a way you can negate this effect.
