Woo not sending JSON - No historical sync - Dev needed

I have a couple of woo sites. One works well with Klaviyo, and one will not work despite my best efforts. The woocommerce integration fails on historical sync.

Klaviyo tech support have helped narrow down a few things:

  • It’s not a plugin (turned them all off)
  • It’s not a permalink issue (rebuilt permalinks)
  • It’s not a user-agent being blocked by my host

They think its due to an error of unknown type on a product page.

I can’t see any errors on any product pages, and Woo’s not flagging anything as out of normal order.

The error generated when attempting a historical sync is “Invalid JSON: Expecting value: line 1 column 1 (char 0)” and indeed, the content is HTML.

The traceback provided by Klaviyo tech support doesn’t point at anything in particular on my site being a problem.

Basically, I think I need a developer who knows Woocommerce and Klaviyo integrations. Anyone recommend someone they trust?
