Hi, I installed calc with 2.1-a2 installer. Installation did work all right. But when opening calc in browser it jams. What could be the reason? I used Ubuntu 14.04 and 16.04 distributions. Only SEVERE error I found from logs is below.

greetings, Heikki

Hi Heikki,

I have just tested on linux ubuntu 16.04.1 and it works fine. I am unable to reproduce this error.

If you provide more details on your environment, i could try to test it with the same settings you have.

Thank you, Mino
