blank page when trying to connect to site

[gil shinar]

Hi all,

I'm trying to upgrade our sugarCRM from 4.5.1. to 5.X. In order to do that, I'm trying to move our sugarCRM stuff from our server to my laptop. I've installed apache2, php5 and mysql. Brought all sugar directory under my /var/www folder and dumped/restored the MYSQL data. When I try to connect to http://localhost, I get the "It works!" message. When I move the index.html to the sugarCRM home folder (sugarsuite) and type http://localhost/sugarsuite/index.html, I get the "It works!". When I delete the index.html file from the sugarsuite folder and run either http://localhost/sugarsuite or http://localhost/sugarsuite/index.php, I get a blank page.
I have tried to edit the config.php and php.ini in any possible way with no success.
I have chown -R www-data:www-data /var/www/sugarsuite and chmod -R 755 /var/www/sugarsuite but still nothing.
The worst thing is that I cannot find any log messages, not in the sugarcrm log file, not in the apache eror log file. The only message I can find is in the apache access log but it does not seen as problematic message.

Can any of you assist please?

Thanks

Gil

Try to enable PHP error messages in php.ini, something like:
error_reporting = E_ALL

Other thing you can try is to make just a new installation of sugarcrm and see if it works

What versions of php and mysql are running on your laptop?

Done that already.

What versions of php and mysql are running on your laptop?

mysql Ver 14.12 Distrib 5.0.75, for debian-linux-gnu (i486) using readline 5.2

PHP Version 5.2.6-3ubuntu4.5

I have additional info. I have added a print line to the index.php file and now I get an error after the line I wrote in the print function. It looks like that:
In index.php file
Warning: ini_set() [ref.outcontrol]: Cannot change zlib.output_compression - headers already sent in /var/www/sugarsuite/include/utils.php on line 2971

I have tried to read about the zlib issue but nothing helped.

Thanks
