Undefined array key “default”
-
Hello,
For the last 2-3 weeks i have found these warnings in my 2 sites. Found on POST and GET requests to cart, add-to-cart and checkout.
FastCGI sent in stderr: "PHP message: PHP Warning: Undefined array key "default" in /www/public/wp-includes/class-wp-list-util.php on line 170" while reading response header from upstream, client: 78.26.35.163, server: www.xxxxxxxx.no, request: "POST /?wc-ajax=sco_checkout_order HTTP/2.0"Warnings are only found in relation to cart, checkout, ajax add-to-cart and as above sco_checkout_order action.
As far as i can see Svea plugin and my theme is the only updates i have done during this period so just wondering if the above warning could be related to Svea plugin?
Brgds
