 * Whenever I press “Activate” on the plugin I get an error that says
 * Warning: Cannot modify header information – headers already sent by (output started
   at
    /wp-content/plugins/woo-product-slider/main.php:214) in wp-includes/pluggable.
   php on line 1179
 * I get this even if I try uploading the plugin manually. Not sure if this is serious
   or not.
