# Invalid XML String

 * People are trying to purchase this product and it keeps throwing an error.
    It
   says payment was unsuccessful contact merchant. On the order it says this Helcim
   Payment Failed – Invalid XML String –
 * The issue is that payments are successfully going through but WooCommerce is 
   ignoring new transactions and not updating the order status or sending out emails.
 * It worked on Sep 8 and there has been no work or new payments done on the website
   until today. There was an update a few days ago so I tried rolling back woocommerce
   and it didn’t fix the problem.
    I deleted and recreated the product and it has
   not fixed the problem. My first assumption was the word “time” is passed by Helcim
   but removing it from the attributes did not fix it.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Finvalid-xml-string%2Fpage%2F2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
