Hi Guys - after upgrading, all html5 ads were unreachable in the back end. The ads show in the list but without a type and clicking it just reloads the same ad list page.
adding a new html5 ad allows me to add the information, but clicking save takes me to the edit screen for the ad immediately preceeding it in the list, not the html5 ad.
Clicking on the ad in the manage ads list results in Call to a member function getExistsZoneWH() on null
the ad shows on the front end
can you please help?
