PNP4Nagios graphs not working for one end user

[tantonou]

Hello,

We are using PNP4Nagios Version 0.6.19 and we have one user who's graphs are throwing a Kohana v2.3.4 error when they click on the graphing icon:
Undefined index: DISP_HOSTNAME.

application/congrollers/graph.php [88].

Since all other users of Nagios are getting to the graphs fine, I'm thinking it's something on his local workstation interfering.

Looking for troubleshooting ideas.

UPDATE: End user was using Opera browser. I downloaded it and installed on my machine. Yes, it broke the graphs.

Removing it did not repair them.

On to PNP4Nagios support.
