Validation error

[islander667]

My cacti was working great, i think this happened after centos upgrade, and now when i want to move a graph to a tree, it shows Validation error on a blank page.

Any help ? what could be wrong here ? this is the first time i am seeing this error.

cacti 8.8.b, cent OS 6.5 final.


Thanks,

SVN has been patched for this already. The Centos package manager will need to update the packages.

You should still be able to add a graph to the tree by going through "Graph Trees" instead of "Graph Management" or "Host Management"

Thanks a lot.

Can you explain how I can upgrade my current Cacti (from Centos repo) to fix this bug ?

I'm having a very similar issue. When I try to place a device on a tree I get the validation error on a blank page.
This is Cacti version 0.8.8b on CentOS 6.5, and placing a device on a tree used to be possible.

I faced the same issue on CentOS 7 installation of cacti from epel. Replacing /usr/share/cacti/graphs.php file with the one found on the following link
http://svn.cacti.net/viewvc/cacti/branc ... threv=7458
didn't work for me. However replacing
input_validate_input_number(get_request_var_post('drp_action'));
string in graphs.php with this:

input_validate_input_regex(get_request_var_post('drp_action'), "^([a-zA-Z0-9_]+)$");

Worked for me.
Good luck

Hi romuald,
thank you very much for your post. I've been it the same situation (CentOS7 + Cacti 0.8.8b from EPEL) and your solution instantly helped me. Great! I'm using (not entirely of my will) CentOS for a new Cacti server, and I'm a bit disappointed by Cacti support of it's package maintainers, especially in comparation with OpenSUSE I've been using before..

Hello,

I had similar problem, but I wanted to apply tresholds from device menu.
And romuald advice really helped me a lot, but instead graphs.php I modify host.php file and after that everything goes smoothly.

Thank you
