Just try new addon MUNIN, works fine all our boxes except one. This was called from WHM menu.
The server was not able to find the document (./munin/index.html) you requested
Please check the url and try again. You might also want to report
this error to your webhost.
cpsrvd/10.6.1 Server at xxx.xxx.xxx.xxx
Installation script seems to ends correctly
Here are our specs:
WHM 10.8.0 cPanel 10.8.2-S120
Fedora i686 - WHM X v3.1.0
Same error I get. I am my webhost, so reporting to myself won't help hehe.
