 * I can install WooCommerce on my site with any issues, but when I try to activate
   it, I get:
 * > Plugin could not be activated because it triggered a fatal error.
   > Fatal error: Call to undefined method CSSMin::minify() in /home4/schumann/public_html/
   > wp-content/plugins/woocommerce/includes/admin/wc-admin-functions.php on line
   > 194
 * I once had it activate using WordPress 4.0 and it seemed to be OK, so I think
   this problem started with the 4.1 update. It sounds like a possible theme issue,
   but I don’t know where to start.
 * Any suggestions would be greatly appreciated.
 * Many thanks,
 * Florian

 * I recommend asking at [https://wordpress.org/support/plugin/woocommerce](https://wordpress.org/support/plugin/woocommerce)
   so the plugin’s developers and support community can help you with this.
