Sugar Community Edition 5.2.0 (Build 5380)
Fedora 9
PHP 5.2.6

It doesn't seem to matter how the file is formatted (csv with double quotes, csv without quotes, tab delimited). I keep getting the same error when clicking the Import Now button:

NOTICE: [8] Undefined index: action on line 45 in file /var/www/SugarCE-Full-5.2.0/index.php

There are only three columns in the csv file (firstname, lastname, and email). I've added die() commands to stop the process so I can ls the upload_dir to verify that the file does indeed get uploaded. There's nothing in the server error logs (apache or php) to indicate what may be happening.

I did recently tighten security on the server, but the permissions still follow these guidelines:

The php.ini open_basedir directive has always been commented out.

It's strange, because Sugar gives that error after confirming the field name mappings. So, it can obviously upload and read the file. Any ideas?

Here are the entire test csv file contents:

FirstName,LastName,Email
Ralph,Wiggum,rwiggum@test.com
Stan,Steamer,steam@test.com

Thank you,
