not able to save setting

Follow the below steps to fix the issue of receiving a message as “Settings not updated” while updating the Settings page. Take backup of the files before modifying them.

Go to the file videosettingsController.php in the following file path, wp-content/plugins/contus-video-gallery/admin/controllers and search for the code,

if ($updateflag) {
                $this->admin_redirect ( 'admin.php?page=hdflvvideosharesettings&update=1' );
            } else {
                $this->admin_redirect ( 'admin.php?page=hdflvvideosharesettings&update=0' );
            }

Replace the above code as below,

if ($updateflag === FALSE) {
              $this->admin_redirect ( 'admin.php?page=hdflvvideosharesettings&update=0' );
            } else {
                $this->admin_redirect ( 'admin.php?page=hdflvvideosharesettings&update=1' );
            }
