– "Warning: Cannot modify header information – headers already sent by (output started at /wp-admin/includes/template.php:1867) in /wp-content/plugins/nextend-smart-slider2-full/library/smartslider/admin/controllers/sliders.php on line 408" error message.

– Can't use slide editor.

– Website's code seems messed up.

– Can't click on buttons in the backend.

– Save doesn't work.

On most websites at the WordPress' SettingsNextend SettingsCSS and Javascript load mode the Normal mode works, but it could have problem depending on the website's Gzip compression, so if there is an error in your website's source code, something is loading in a wrong place when the Nextend plugin is activated, then try out the other two options.
