I have gone through all the steps given on the instructions for installing moodle, but when I try to access the /admin page, I get nothing but a blank screen with a tiny picture of a hammer on it.
Can anyone help?
Well, that's a new one. I have no idea.
Try renaming the admin folder to "moodleadmin", and changing the setting $CFG->admin in config.php to match.

I have tried this as I have similar problems... It seems to work although I now get this message:
Bad $rs in GetInsertSQL. Connection or SQL invalid. Try using $connection->debug=true;
from the 1st Home -> GPL License Page... Next the Home -> Setting up database Is a SUCCESS.
When I click CONTINUE all I get is a blank screen, similar to http://moodle.org/mod/forum/discuss.php?d=5241.
Any ideas on what to try next ?
PS I am trying to instal moodle 1.2
I've exactly the same symptom. I think it's because I installed a recent version of the module Workshop in Moodle 1.1.1 installation.
I'm not sure though, because I also installed the module attendance to test it, and maybe this one is the culprit !

I have a similar problem.
Having successfully tested moodle for months on a microsoft platform, I thought I'd be all clever and put it on a linux setup.
The result is at http://www.plumptononline.ac.uk
it's obviously doing something, no error, and a sort of minimal html in the source.... but I can't work out what I've NOT done...
I have followed the step by step, and the general install, and am at a total loss, though I have learnt a shed load about using Linux.
Any suggestions most welcome.
The FAQ "A" all blank seemed to be what I was looking for, but If I try to qualify the address to anything else it merely suggests try usr/moodle
I turned on phpinfo, and under dbx it says supported databases: Mysql.....
I don't want to go and put this server over to IIS, help!

A tip: Check your database settings carefully.
If I remember correctly I also got the blank screen syndrome when Moodle couldn't find/connect to the database.

Thanks I will check.
Not sure what or how to check. the linux setup required a command line in the X terminal to spark up the database compared to the easy php web screen I'm used to.
Could it be anything to do with the sql service listing under services as mysqld rather than mysql?
can't be as I logged in mysql -u root
and was able to create a database.
Check if the mysql deamon is running.
# ps -aux | grep mysql
Should show something like
mysql 772 0.0 2.2 15504 5756 ? S 2003 0:05 /usr/sbin/mysqld
mysql 778 0.0 2.2 15504 5756 ? S 2003 0:04 /usr/sbin/mysqld
In Moodle config.php
$CFG->dbtype = "mysql"; // mysql or postgres7 (for now)^M
$CFG->dbhost = "localhost"; // eg localhost or db.isp.com ^M
$CFG->dbname = "moodle"; // database name, eg moodle^M
$CFG->dbuser = "root"; // your database username^M
$CFG->dbpass = "a_valid_password"; // your database password^M
Maybe you haven't set a root password (not advisable). Then
$CFG->dbpass = "";
Cheers

get this:

not sure if that means its up or not... think I saw something somewhere about safe mode? I'll have another look, but I was sure the safe mode thing was disabled when I queried php

Re: blank screen when trying to access /moodle/admin

tried changing database user to root, no difference.
Could the firewall be blocking it somehow?
I seem to remember when i installed moodle about a year ago I had to turn off Zone Labs firewall to make things run ok. UI only have the default linux firewall at present... and realise announcing my firewall status on a web forum is dumb, but ....
I will try and report back

Ok so Mysql is running
I've checked the firewall wasn't hampering things.
PHP seems to be ok
but no moodle, just a blank page.... calling Martin moodle maker... any ideas... else I'll have to use IIS (Sob)

What sort of Linux is it? Redhat?
Look in /var/log/httpd/error_log ... anything pertinent?

Re: blank screen when trying to access /moodle/admin

when the blank pages show, there are no error messages created.
I get errors if I try for wrong directories, and these show in the logs.
I'm not sure if the SIGTERM thing is releveant, I tried restarting the service, just to see if anything else happens.
I'm, guessing this is just the log of it shutting down.

I did some testing and my version (CVS from two nights ago) reports the following when it cannot connect to the database.
Error: Moodle could not connect to the database.
It's possible the database itself is just not working at the moment.
The admin should also check that the database details have been correctly specified in config.php
Database host: localhost
Database name: vle
Database user: user
---
But what generates a blank screen? I'm fumbling in the dark but is it maybe some of the paths in your config file that aren't correct?
Sorry that I only can give you suggestions and not actually tell you what your problem depends on
Is there anybody else who can give Rob some clues?
Cheers

just spent a little time checking the webserver works
it seems ok, it certainly serves up fish:
www.plumptononline.ac.uk/moodle/index.html
still stuck as to why moodle isn't a goer
As far as I know there shouldn't be an 'index.html'-file in the moodle directory.
Could you please create a file named phpinfo.php
with the following content (no spaces in the beginning or in the end of the file)
<?php
phpinfo();
?>
and post the url to this file here.

Tried fresh install of linux, and moodle.....no change...
the link to index.html was just to test whether apache was really working. I placed a learning object in the moodle directory, and it did work for me... though obviously not for you....
http://www.plumptononline.ac.uk/moodle/phpinfo.php is the php diagnostic, which loooks ok to me, mind you I wouldn't know if it was right or wrong....

good, I'll try that as I'd just about pinned it down to something like that by changing the db name which made not a jot of difference, but if I changed the type of db I got:
Fatal error: Cannot instantiate non-existent class: adodb_notmysql in /usr/moodle/lib/adodb/adodb.inc.php on line 3211
I've got no idea how to install a php-mysql RPM, beingba simple windows operator, but will do a quick web search.... downloaded the rpm, and trying to work out what to do with it...

You got the install command right, but the wrong RPM package.
php-mysql.rpm (not php.rpm)
It's a separate RPM - it comes with Redhat (on your disks) but isn't installed by default.

not sure what to do now. can't seem to install the rpm, I'm stuffed. Home to bed for a bit of kip, and look again in the morning.
