simplexml_load_string error

Hi! I’ve recently got this error: Warning: simplexml_load_string(): ^ in …/woocommerce-currency-switcher/classes/woocs.php on line 2867 Error: Cannot create object. My website was down because of it. I tried to update plugin but it failed. I removed all the code where I use $WOOCS global variable and it helped. Can you help me with this issue?
