[ERROR_MSG] => String could not be parsed as XML

Hi guys,

My form data cannot get into my sheet.

There is a same topic but no solution at the end.
https://ww.wp.xz.cn/support/topic/error_msg-string-could-not-be-parsed-as-xml/

I have already checked that cURL is enabled using phpinfo().
cURL support enabled
cURL Information 7.62.0

What can I do?

Thanks
