Thanks for your interest in OrangeHRM.
This is in regard to the previous two postings.
From what you have said, you have installed OrangeHRM manually without the help of the in-built web-installer. Since you were forwarded into login.php when you entered http://localhost/orangehrm
you have created the Conf.php too. I hope you used dbscript.sql to create the database since that is the one required if you are doing a manual installation. (refer OrangeHRM FAQ; http://www.orangehrm.com/home/index.php?option=com_content&task=view&id=22&Itemid=54
for more details on how to install OrangeHRM manually)
If you did a manual installation the login credentials would be;
If the login results in a blank screen, as most PHP developers would tell you it is because there is an error in the page, and since by default (in PHP5) error display is set to off you get a blank screen. Now don't be mistaken into the error you have received (said in the second posting, that is due to something else). The only means of debugging I recommend in this case is Apache error log, which would contain all the errors encountered.
Having PHP running as CGI mode reduces performance and functionally there are certain limitations while being more secure. To run PHP in CGI mode you have to re-compile PHP with --enable-cgi in configure command. I don't think this has anything got to do with your problem.
Running the command line "php -e -f /var/www/html/orangehrm/login.php" will not help your course. PHP command-line is meant for stand-alone PHP scripts and not meant for scripts meant to be processed by a Web Server. "REQUEST_URI" is a environment variable set by the web-server and because it was not set when you ran the script command-line you get the error.
So the best thing you can do is to quote whatever error that is captured in the Apache error_log.
Hoping to hear from you soon.
