Nagios Support Forum

Hello,

I just upgraded Nagiosxi to 2014R2.0 and I am no longer receiving email notifications. When I go to test the email notifications I get a page with an error:

The website cannot display the page

The address is: https://xxxxx/nagiosxi/admin/testemail.php #xxxxx is the server name blotted out.

This happened after upgrading NagioxXI. I downreved to a backup and it still didn't work, so I brought it back to the new version.

Redhat: 6.6
Nagios XI 2014R2.0

Alright. Lets check a few things:
1. Check for apache errors: 2. Check your browser console for errors (with ctrl-shift-j). Post any relevant ones here.

3. Check the permissions on the tesemail script:

How was php installed on this system?
The function mbstring_convert_encoding() should be part of a default php install, unless php was compiled or installed from a non-standard repo:

[snip] This requires that PHP has the mb_convert_encoding() function. Your PHP installation lacks this function (PHP needs the "--enable-mbstring" when compiled).',0),
