Unable to Add New Device After Upgrading to 0.8.8a

[Cedrick]

Windows 2008R2 Std, NET-SNMP version: 5.5, RRDTool 1.4.x, PHP 5.3.8

Recently upgraded from Cacti 0.8.7i to 0.8.8a by following instructions on http://www.cacti.net/downloads/docs/html/upgrade.html and applied SNMPv3 patch from http://www.cacti.net/download_patches.php. When I try to add a new device I get a HTTP Error 500 Internal Server error message while trying to display http://localhost/cacti/host.php. I've checked permissions on the new Cacti \log and \rra directories and those match the permissions on the old cacti install. The thing that bothers me is that I can create new graphs from a device that already exists just fine and they (and existing graphs) are drawn. I just can' add a new device.

I've been looking through logs and haven't found anything. Any suggestions to help narrow down the problem would be greatly appreciated.

you can restore old "lib" directory to cacti.
It will be fine.

You sure the other cacti .php files have the correct NTFS permissions? Make sure the web service account has read/execute on them all.

Thanks for your replies. What I wound up doing was restoring the Cacti server back to 0.8.7.i and updated to 0.8.8a again (which worked this time). Must have screwed something up before.

Just an FYI that that I found that after applying the snmpv3_priv_proto_none.patch it caused the issue as it updated the /cacti/lib/api_device.php permissions:

wget http://www.cacti.net/downloads/patches/ ... none.patch
patch -p1 -N < snmpv3_priv_proto_none.patch

After changing the permissions on the api_device.php file I could add new devices.

reapplying security is called out in the guide -http://docs.cacti.net/manual:088:1_inst ... ly_patches
