Undefined index error

Undefined index error

I'm running Moodle 1.6 as production server and Certificates have been working fine until this weekend.  On Sunday I added the Certificate module and Activity Locking to what I hope to become my new production version of Moodle running 1.9.4.

I did not work yesterday (Monday) but when I arrived today I find that the 1.6 site was down yesterday.  The config.php file had a trashed top line.  The people on duty restored a backup version of config.php and restored Moodle to operation. 

Now the issue is the Certificates no longer work.  When I try to view a certificate I get the message:

Notice: "Undefined index:p in /srv/www/htdocs/moodle/config.php on line 1"

Warning:  Cannot modify header information - headers already sent by (output started at /srv/www/htdocs/moodle/config.php:l) in /srv/www/htdocs/moodle/lib/fpdf/fpdf.php on line 1022

FPDF error:  Some data has already been output to browser, can't send PDF file

I know someone out there must know what the issue is.  Please help me since my job is on the line.

Thanks,

Bill

Hi Bill

The server outputs an unnecessary NOTICE which causes the PDF output to fail.

Add this line to the top of config.php (and possibly also fpdf.php):

error_reporting(E_ERROR);

It should instruct the page not to output any NOTICEs.

Thanks Kaalgat, you nailed it.  Everything is working again. 

If you don't mind, do you have any suggestions as to why this started happening all of a sudden?  As I posted before I am getting a new instance of Moodle ready to release to our users but nothing is shared between them as far as I know.  Separate folders, versions of both Moodle and the Certificate mod, separate tables in the mySQL database, etc.

Thanks,

Bill

Hi Bill

Pleasure.

I think it could be a PHP setting on the server that shows "Notices, Warnings and Errors", instead of just "Errors". An administrator could have changed it, or maybe upgraded the PHP on the server.

For a developent site you would like to also see the warnings, but for a production server you only want to see the errors. The php.ini file on the server has these values available that could be set accordingly:
error_reporting = E_ERROR
display_errors = Off

Or maybe that one line could have been missing from the files that your ISP replaced from the backups.
