 * We’ve had Oliver POS for a few weeks/month now with no issues, but yesterday 
   we started getting the following error anytime we try to update our shop or upload
   media files:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/customer/www/cincysc.com/public_html/wp-content/plugins/oliver-pos/includes/
   class-pos-bridge-order.php:1) in /home/customer/www/cincysc.com/public_html/wp-
   includes/functions.php on line 6362
 * This seems to be caused by some conflict between Oliver POS and our existing 
   wordpress headers.
 * Any thoughts on how to solve? This is stopping us from doing anything to update
   our shop, add products, etc.
