I just found out that your plugin replaces functions names from WordPress core files and manipulates the file "wp-includes/widgets.php".
This ist totally against best practices and WordPress coding standards. One should never ever touch core files.
It leads to breaking functionality with themes and/or other plugins. What is with plugins relying on the function "is_active_sidebar"?
I hope you could release an update of your plugin which changes the code this way that all ins in your plugin and that it never touches any core files.
Aren't the hooks/filters of WordPress enough for modular plugins? Just wondering...?
Thanks, Dave :)
