How to modify less in ES template and force ES to recompile

Hi There,

I just upgraded to the latest ES v2.0.17 and going to the override route as you guys suggesting instead of creating my own theme. So, I went to modify custom/default.less and it created a copy on my template:

<template>/html/com_easysocial/styles/custom/default.less

Then I went to load http://site.com/index.php?option=com_easysocial&;compileCss=1 as mark suggested to force ES to recompile theme css. It seems to recompile but it does not include my default.less override.

Why?

Thanks,

Jackson
