Hello!
Well, after some weird stuff happening in the server, I've had to disable Wyomind ElasticSearch module..
However, when I now try to edit a product from the catalog I get a reference to:
'Wyomind\ElasticsearchCore\Model\Config\Source\ProductWeight' not found in /var/www/site/lib/internal/Magento/Framework/ObjectManager/Factory/AbstractFactory.php:93'
However, the catalog search engine is MySQL.
Am I missing something?
I do know I should upgrade to 2.4, currently running 2.1.6.
