I've uploaded the latest PD map via ADD PROJECT and ticked the "Cache" checkbox. At a certain moment I got the error (stacktrace below) and cannot access the admin panel anymore from the same browser (Safari). Login from Chrome worked. I believe the error happened around 35% of drug data caching, but I'm not sure. Caching process seems to be frozen at 38% of drug cache. I've uploaded the map around 12:00, it's 15:30 and it's still not finished. I will try to post an update in one hour or later. ------------------------------------- HTTP Status 500 - User cannot be null type Exception report message User cannot be null description The server
