I am trying to get my quantity field to allow decimals (we are charging by the hour, so we need 1.5, 2.5, etc to be options)
I referred to another post that suggested I copy/paste the code to my Theme's functions.php file from this link: http://gravitywiz.com/2012/05/10/enable-decimal-values-in-quantity-fields/
However I am getting a header output error and now the entire site is down. This is my error:
Warning: Cannot modify header information - headers already sent by (output started at /homepages/25/d420306737/htdocs/KSS Website/wp-content/themes/thestation/functions.php:30) in /homepages/25/d420306737/htdocs/KSS Website/wp-includes/pluggable.php on line 881
How do I fix?! Thanks!
