Recent upgrades to php for taking care of the denial of service exploit have now included a PHP directive for max_input_vars.
Without setting in php.ini, it defaults to 1000 which won't render the gradebook as before.

Uhhh, do hope php has been upgraded or your site could suffer a denial of service fate! :(

This could result in an issue with Moodle gradebook where there are more than x users to display in the grade book.
See:
http://moodle.org/mod/forum/discuss.php?d=184102#p846640

To find out if that's the issue, do as a poster suggest and search the error logs:

On a CentOS box as root user:
fgrep max_input_vars /var/log/httpd/error_log

If you have the issue something like this will be found:

[Mon Jan 23 16:25:18 2012] [error] [client x.x.x.x] PHP Warning:  Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0, referer: http://site/moodle/grade/report/grader/index.php?plugin=grader&id=99&sesskey=PqQGn8IIuL&edit=1

The fix:  edit /etc/php.ini and include the setting:

; added 2012-01 gradebook issue
max_input_vars = [something above 1000]

the ; line above is a comment - good idea to add comments of your own when changing ini for php.

Must restart apache: /sbin/service httpd restart

Check your php info in Moodle and you should see the new settings for the variable.

or while you are at the command line already:

php -i |grep max_input_vars

should show:
max_input_vars => 5000 => 5000

Search for TCEA using GeoReader

Example curricular application:  since I taught Social Studies ... bet every town in Texas has some historial landmarks either in the city/town limits or near by.  Now wouldn't be interesting to use TCEA Social Studies Collaborative and ask those that desired to do so, share their local history and interesting points via GeoReader and Moodle.  http://moodle.tcea.org/sscolab/

Y'all might remember a thing mentioned called LTI (Learning Tool Integration).

Hmmmm … missing in action: Epsilen (but they are a closed system … cept for New York Times content).

Well, in M2.2+ there is now an LTI tool (consumer) and just today an add-on for M2.2 called LTI Provider.
http://docs.moodle.org/22/en/LTI_Provider

Have it installed in two instances of M2.2 for the Moodle Academy 2012 and in a Sandbox.

It takes some tinker time, but it does work.

Shameless Moodle Academy 2012 ad: Moodle 2 the Good, the bad, and the Ugly!  (GBU!)

http://owncloud.org

OwnCloud setup as a WebDAV in Moodle even though it's a standalone service on another server.  Could mean mega admin if NOT using some common authentication method - LDAP.  Think there is a plugin now for OwnCloud that will do MS Active Directory LDAP … if using a MacOSX server (InfoDirectory) or eDirectory of Novell, then more 'investigation' required.  Same is true of mount points, me thinks.

In Moodle setup of a WebDAV repo:
Name: Whatever you want to call it
WebDAV type: http
WebDAV server: just the FQDN of the host.  Example: sos.tcea.org
WebDAV path: /path on other server relative to web root (/owncloud/
files/webdav.php
Autentication: WebDAV basic
no port
If one doesn't use server user and password, no prompt for login?
(this could possibly be fixed).

So the repo one is setting up has already been created in OwnCloud.
And in the Moodle config of it, if one already gives a login and
password to access, what can others do in the OwnCloud collection to
which you've pointed?

Have a link to a video in OwnCloud (WebDAV) as a URL resource … the
video has to be shared in OwnCloud and the share link has to be used.
Moodle has no interface to the administration of a WebDAV space - just
like Google Docs.

So once I have it linked (popup in new window) then users can see the
URL:
http://sos.tcea.org/owncloud/apps/files_sharing/get.php?token=94d400b...

One will get some practice at duplicating a resource tinkering with
which method is 'better'! ;)

Other methods chosen to view may have some issues or un-desired
'experience' or ability for end user … embedded, auto?

It's somewhat like GoogleDocs Repo … think Teachers would desire to
use the one that would show the UPDATED doc/resource should there be
updates made.  Different student who is turning in an assignment,
isn't it?  Don't want the student to be able to turn a doc in and then
go back to Google or OwnCloud repo to change/update the doc, do we?
Hmmmm, some intelligent and enterprising youngsters could setup a
'business' (docs4class.org), could they not?

That's the kinda of exploration one needs to put Moodle 2 through ...
afraid one has to think Yin/Yang from the viewpoint of Teachers and
Students (while, at the same time, Moodle Server Admin - who has less
control than in 1.9.x to fix issues - fewer back-door methods available).

Create a directory /home/winserver.  Created by root user.  No permission changes needed root:root is ok.

The following is for CentOS servers (RHE flavored).
Replace [value] with appropriate values for your situation.

Archive script runs after backup below

Archive script

echo 'Mounting Windows Server';

mount -t cifs -o username=[username],password='[password]',rw,uid=500,gid=500 //[winserverIP]/[folder] /home/winserver;

echo 'Archiving sqls and tars - be patient!';

echo 'Archiving sqls ...';

cp /home/backup/*-$(date +%Y%m%d).sql /home/winserver;

echo 'Archiving tars ...';

cp /home/backup/*-$(date +%Y%m%d).tar /home/winserver;

echo 'Archiving completed.  Listing files.';

ls /home/winserver;

echo 'Unmounting Windows Server';

umount /home/winserver;

echo 'If no files found, unmount OK!';

ls -l /home/winserver;

echo 'Done Archiving.';

Backup Script

cd /home/backup;

tar -cvf /home/backup/moodle-$(date +%Y%m%d).tar /var/www/moodledata /var/www/html/moodle;

mysqldump -u [mysql-user] -p[password] [db] > /home/backup/[db]-$(date +%Y%m%d).sql;

echo 'Done ... listing ...';

ls -l /home/backup;

The above scripts are used on production servers.  Dis-calmer (author did spell it correctly): your mileage might vary.  Author not responsible for it's use or mis-use, etc..

NOTE: the scripts could be converted to something 'Windows'.  If anyone does, please share back!

Interesting 'finds' in a CVS updated Moodle 1.9.12+.  Un-documented?

In [YOURMOODLE]/admin/[name_of_file_below].php - which should mean only admin level users can execute AND must be logged on to execute.

innodb.php

Appears to be a script "Convert all MySQL tables from MYISAM to InnoDB".

If moving to 2.1 this step is either before (preparing to move) OR after moving to 2.1. With this, one could accomplish that BEFORE the move.  No 5 or 6 step guru-ish knowledge of phpMyAdmin required (just 'guts' to try it!  BACKUP BEFORE ATTEMPTING!).
Truth in advertising: have NOT tried it yet!

health.php

appears to show problems with Moodle - and makes recommended solutions.
Here's one:

The user account your are connecting to the database server with is set up without a password.

and another (which I've seen recently on Moodle.org):

Your PHP configuration includes an enabled setting, session.auto_start, that must be disabled in order for Moodle to work correctly. Notable symptoms arising from this misconfiguration include fatal errors and/or blank pages when trying to log in.

Dis-calmer (nope, spelled it right!) ... like programmers who make no claims and who take no responsibility for user actions/abilities, the author of this article also makes similar 'dis-calmer' - take no responsibility for using them, don't 'support' them.  If you didn't make a backup before trying, why NOT? ;)
