I started having the same issue about 2 weeks ago, and I was on my website When it happened. I had updated a few plugins right before the latest woocommerce update was available, so it doesn’t seem like a Woo issue. I don’t recall which ones they were exactly, but I’ve been using each of them for at least 6 months without an issue. When I clicked on one of the product pages, the display became what looked like some type of text/coding. I thought that the site had crashed due to a bad plugin update, but it returned to normal 5-10 minutes later. Ever since then all of the orders return a Texas IP address of 192.185.144.26. This is a severe problem, since any automated anti-fraud plugin can no longer be used. All transactions get flagged as fraud due to the bad IP.
