Finally, the problem is isolated and I could resolve the problem. Below is the process I followed, which may be helpful for others..
My server details:
Apache 2.2.3
PHP version 5.2.4
MySQL version 5.0.22
Client: IE 7.0.5730
1. Tried to run the index.php through CLI and noticed the it is working fine.
Command used : php index.php
2. Modified the following files to see what is going wrong:
a. application.php b. CompanyWebsite.class.php
c. OwnerCompanyDnxError.class.php
3. It is identified the exception was not handled by php through browser.
4. Confirmed that php exception handling problem by executing small php file check_exception.php (the file is attached) from browser.
5. Checked the installed php packages by executing : rpm -qa |grep php command and noticed some modules of php 5.1.* were installed.
6. Removed the php 5.1. related components.
7. Re-executed the check_exception.php from browser and voila, the problem is resolved.
8. Re-installed opengoo 1.5.2 and every thing went smoothly and I could create Company, admin accounts etc. Now all things are working fine.
The basic problem for was due to conflicting php installation. If you see the blank page after successful installation, I suggest please check whether exception is handled properly because that only will take you to further steps.
Request for the development team:
In the installation process, please add a routine to check exception handling is working fine and throw message about the same. This will help lot of users, as I can see from forum that lot many queries are pending for the blank page problem after successful installation.
It looks Great peace of software, let me explore....
Thanks and regards.
