The variation pages (like this: product/?v=55) don't show up, the sites are white / empty. There is a php error, that only appears in the error log of the webserver:
AH01071: Got error 'PHP message: PHP Fatal error: Nesting level too deep - recursive dependency? in /var/www/vhosts/example.com/httpdocs/example.com/www/modules/contrib/commerce_xattributes/modules/commerce_cattributes/src/Plugin/Field/FieldWidget/CorrectProductVariationAttributesWidget.php on line 208'
Disabeling the if-routine resolves the problem
// The returned variation must also be enabled.
if (!in_array($selected_variation, $variations)) {
$selected_variation = reset($variations);
}
Closed: won't fix
