Fatal Error Activating on WordPress Multisite

Hi,

Thanks for your hard work I love WooCommerce!

I’m importing my site that uses woocommerce to my multisite installation and I need to install the plugin. I’m getting this error.

“Fatal error: Access level to WC_Background_Emailer::task() must be public (as in class WP_Background_Process) in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/woocommerce/includes/class-wc-background-emailer.php on line 0″

I tried changing this line of code:

” protected function task( $callback ) {”
to
” public function task( $callback ) {”

And received 500 errors on the site.

Do you have any suggestions of what I can try to fix this error? (It’s critical for me for moving forward.)

Thank you for any and all of your help!
