I use Zanata on my private server and I just got a severe issue. I can't see inside my project anymore. You can see it directly here: http://tools.tsubook.net:8080/zanata/explore (try to enter the project Tsubook).
Step to reproduce:
1- Open website
2- Go to explore
3- Click on a project
4- An error message "No errors" appears
Screenshots and logs attached (the error begins at line 350).
Debian 8.6 x64
App server release codename: Kenny
App server release version: 2.2.0.Final
WildFly Full version: 10.1.0.Final
Zanata version : 4.0.0
