Report crash


Hi to all,
I record some data the report was working properly, I assume that the GPS positon of the record was not taken due to a missunderstanding of the operator.
At this point I re open all the record and point on the map the position and save it.
Now as I try to open the report the pages on my browser became white.
The data are present, the position is correctly plotted on the map but non report are available.
Can you help me?
This is my first time using KoboToolbox.
Many thanks.
