I am running Magento 2.2.2 and suddenly the products cant be saved anymore. Clicking the save button has no effect at all. There are no errors in the console. The network tab in Chromes dev tools shows no traffic when the button is clicked. I redeployed, cleared cache, nothing helped.
Any ideas where to start looking?
var/log/system.log
orvar/log/exceptions.log
give any hints?
