Meeting + Call Invite Failures SCRM 4.5.1

[carlwilk]

Hello Forum Members,

Im having problems with a fairly new installation of SugarCRM. When I try and schedule a call or meeting request the process fails. Im presented with a blank white screen. There are no errors in the apache log and only an entry showing a successful page hit in the apache access log.

Im using SugarCRM 4.5.1 with the Ajexa mail marketing features.
MySQL 5.0.67
Apache 2.2.9
Fedora Core release 4
PHP 5.2.6

I can start looking at code but dont believe this is the answer. Has anyone else come across this? Anyone know of an easy fix?

Cheers,
Carl

Been doing more trouble shooting on this but not really getting any closer to a resolution. I'm pasting extra information in just in case someone sees something obvious that I am missing.

Apache access log entry below - only one. There is nothing at all showing up in the error log.

203.2.3.4 - - [19/Nov/2008:09:19:51 +1100] "POST /index.php HTTP/1.1" 500 1850 "http://my.domain-name.com/index.php?module=Calls&action=EditView&return_modu le=Calls&return_action=DetailView" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)"

Although the page is showing as blank, if I view source I can see the following code.
