4.5.1h: Admin - System Settings page not displayed

[wsiedler]

Hi!

I am running the open source version on this setup:
OS: Red Hat Enterprise Linux 5
SugarCRM: 4.5.1h
Webserver: Apache 2.2.3
PHP 5.1.6
MySQL 5.0.22
Just for the record, on my client I am using Firefox 2.0.0.10 as webbrowser.

The system was recently upgraded from SugarCRM 4.5.1d to h.
Everything seemed to work smoothly, but today I discovered that the System Settings page from Admin area is no longer displayed. There is no error message, the page just remained empty below headline "System Settings:". The error log shows no record for today at all.

Quite unpleasant as I wanted to try LDAP authentication against Fedora Directory Server.

Unfortunately, I don't have the backup from before the update available anymore for a comparison.
An older 4.5.1b version still displayed the page properly.

Can anybody with Sugar 4.5.1h verify this behaviour?
And/Or advise me how to get this page back?
Or is it possible to enable LDAP authentication directly in the PHP code?

I would appreciate any advice!

Thanks and regards,
Wolf

Quick answer to self:
Better keep an eye on file permissions.

After giving full write access to subdirectories
./cache/
./custom/
./data/
./modules/
everything was displayed as desired.

Case closed.
