Hi Federica, Thank you for your tip. Yes, I disabled caching completely. And refreshed browser. This however did not solved the issue. We found the cause of the problem. It had to do with server permissions (403). The host told us there were no recent changes server side. We did nog made any recent changes PS / module side. The weird thing about this, changing permissions did not solve the problem. Even the host could not solve issue by running permission script. We moved the site to other host and problem was solved !?? New host is running same php and MSQL version
