Hi,
I’m having the same issue with the lastest version of Woocommerce and the Cost of Goods Plug-in. When I try to add a backend order, the site crashed and I see a 500 error.
The error messages in the log are about PHP memory exhausted: 2023/08/29 09:29:27 [error] 11759#11759: *282986 FastCGI sent in stderr: “PHP message: PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in /www/detailingaddictcom_762/public/wp-includes/functions.php on line 650” while reading upstream, client: 193.151.184.63, server: http://www.detailingaddict.com, request: “POST /nl/wp-admin/post.php HTTP/2.0”, upstream: “fastcgi://unix:/var/run/php8.0-fpm-detailingaddictcom.sock:”, host: “www.detailingaddict.com:32259”, referrer: “https://www.detailingaddict.com/nl/wp-admin/post-new.php?post_type=shop_order”
I have not yet tried turning off the 2 options the topic starter is talking about, but at least previously it worked with those options on.
