Can't see any graphs using tsung's webui

[Sven Scholle <sven@shelldog.de>]

Hi

I currently use tsung for stress testing. In the graph section of 
tsung's web UI, there aren't any graphs. The requests of the graphs get 
403 status codes as reply.

The inets_error.log contains:
[20/Mar/2022:21:33:03 +0100] access to 
/es/images/graphes-Users-simultaneous_tn.png failed for 127.0.0.1, reason:
"mod_esi: Client not authorized to evaluate: 
images/graphes-Users-simultaneous_tn.png"

Version installed: 1.7.0-3.1

I can't find any hints in the documentation. Do you have any idea?

Thanks.

Regards,
Sven
