Hi, I deactivated woocommerce but the second I deactivated the site went down. I am getting HTTP Error 500.

After investigation, the error is “PHP Fatal error: Class ‘WC_Payment_Gateway’ not found in /home/progres4/public_html/wp-content/plugins/woocommerce-paypal-pro-payment-gateway/woo-paypal-pro-gateway-class.php on line 3”

Whats the fix for this error? Thanks in advance guys

Would I loose all the products and data if I disable plugin?
