I'm not certain if I'm getting this across correctly.
It appears that this plugin does not use "sidebar.php" from custom themes properly.
My theme (weavertheme.com) Weaver II Theme causes an error when using the plugin. The error disappears when I remove the file sidebar.php from the themes' directory.
The theme weaver, doesn't use sidebar.php, rather it uses it's own custom sidebar.php.
Is there a better way to code the plugin so that it uses the current theme's sidebar.php file instead?
If you need more info, let me know what...
