Hello,
This error happens because, the plugin uses the latest version of jQuery. Other plugins find it incompatible. I’ll make a fix for this soon. But by now please make this change and confirm the working.
– Open super-rss-reader.php
– Delete or comment (wrap the lines within /* and */) the lines
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery’, ‘http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js’);
wp_enqueue_script(‘jquery’);
Thank you.
