Hi Alex
I faced the same issue on my website and resolved it however I believe an update is required to fix this issue. Here is what happened.
Basically if I run the website on PHP 8.1, I receive the same error as reported by malic but if I switch the PHP version to 7.4, it works without any error.
I believe a fix should be done in the plugin so it works with PHP 8.1 as well.
Hope it helps.
Hi
Sorry for late response.
I tried to do the same as you requested above however the dropdown there does not have the option for “Woocommerce Google Product Feed” hence I raised the ticket here.
