Were did you get that code from? There's either an issue with including a file twice (e.g. by a broken plugin) or an issue with that file itself

[gandalf]

Please post list of installed plugins.

[vel]

I have installed Plugins like Nectar,Reportit,Realtime. All of this three plugins are working fine.

[gandalf]

Please deactivate those plugins one by one and retest. Do NOT uninstall, deactivation should be enough

Thank you for your help.


Hi gandalf,
I disabled my cacti plugins one by one and After disabling the each plugin i clicked on graph managemnt/Data Source link in console page still i am getting the blank page in the browser.

Pls help me to fix this issue.


Thanks,
Vel R

[gandalf]

So my assumption blaming the plugins was wrong.
You told me, that Cacti was fetched from cacti site itself. So I should have the same code. But I can't reproduce that issue. I'm convinced, that this is due to including the global.php file twice. So I'm in fact lost.

I have the same issue.

I install a fresh http://www.cacti.net/downloads/cacti-0. ... 3.1.tar.gz and nothing else.
After install process, all work exept that I can't show "Graph Management" menu.
I have this error on http log :

Hello Gandalf:

After many years, I have the same problem.

I installed cactis using this tutorial: https://gist.github.com/anamorph/dadeb22340ca4deec5f2.

I migrated scripts and rra from an old server to a new one (with the clen isntallation).

Now, when I access to "Graph Managment" I see a blank page. In the apache log I see:

Code: Select all

apache log: PHP Fatal error:  Cannot redeclare graph() in /usr/share/cacti/graphs.php on line 1337

and:

PHP Fatal error:  Cannot redeclare graph() in /usr/share/cacti/graphs.php on line 1337, referer: http://myserver/cacti/graph_templates.php

I did a grep to search other graph() inside the directory, but there is only that. I don't have plugins installed.

I have the right permissions, etc. I even gave chmod 777 to everything to see if that was it.

-------------
It appear that the PHP version may cause the issue (http://comments.gmane.org/gmane.network.cacti.user/6300), but they say that new versions of cacti should be fine. I have PHP 5.3.3, and lates cacti version

Hoping you can help us!

Your,s
Cactus
