Hi, can you give me some help about an issue regarding showing public statistics? After submit answers and click on "view statistics" link on the next page, I´,m directed to a page, like below. I´ve made all statistics configs, like set the "show public statistics" on global and question configs, but the error persists. There´s another config I must do, that I´m probably skipping? Thank you. 

A timing issue between PHP and nginx maybe.

Do you manage the server ?
Do you have access to nginx error log ?

Can you try with only one question shown without graph to start ?
