Re: [Server-devel] Database error troubleshooting
Regarding below, on the Moodle forum I was advised to try deleting the Moodle config.php file (after backing up) and it would then bring up the install page to regenerate it. However, when I test this on my local XS (0.6) it says install.php not found. Looking for tips how to regenerate the database connection. David Subject: Re: [Server-devel] Database error troubleshooting Would appreciate any more tips on why the Moodle database connection is in error. My resource person in PNG has repeated tests on the XS and confirms service postgresql status and service httpd status both report postmaster/httpd services are running OK, but the Moodle home pages states database error. I can research this error for default Moodle installations but don't know if there are any specifics related to the XS Moodle configuration.

Re: [Server-devel] Database error troubleshooting
I remain ignorant of how to solve this problem, however I have a random suggestion based on your observation: On Fri, May 11, 2012 at 11:38:07AM +1100, David Leeming wrote: > service postgresql status - gives "postmaster is stopped" Then try service postgresql start then check again with service postgresql status and if you no longer see "postmaster is stopped", check if the problem on an XO persists, and if so, check postgresql status again and then service httpd restart -- But this is blind prodding without understanding the real cause of the problem, sorry.

Re: [Server-devel] Database error troubleshooting
Thanks, I don't know how that might have come about as the server is not accessed via the terminal. It is quite important to us to try and find a solution on site. The chap there is able to follow simple instructions using the terminal. So any help greatly appreciated...
