Hi Martin,

If I request a statistic graph via admin area, I look a page without image automatically-generated, with the following path (visible into html code):

<IMG BORDER=0 SRC="http://www.territorioscuola.it/moodle/course/loggraph.php?id=2&user=1&type=userday.png&date=0">

How to make for to resolve this?

Cheers,
Davide

If you go directly to the URL, ie:

http://www.territorioscuola.it/moodle/course/loggraph.php?id=2&user=1&type=userday.png&date=0

... you should see error messages that will explain what's going on ...

Cheers,
Martin

I've view these following error messages:

Warning: Could not read font in /home/mhd-07/www.territorioscuola.it/htdocs/moodle/lib/graphlib.php on line 1293

If this is a set permission problem, on which files or directories I would
have to set up this permissions? With which sequences rwe?

Many Thanks for your patience.smile

It might be a permissions problem ... the file that is being read is this one:

/home/mhd-07/www.territorioscuola.it/htdocs/moodle/lib/fonts/arial.ttf

This is probably quickest:

cd /home/mhd-07/www.territorioscuola.it/htdocs/moodle
chmod -R ugo+rx lib/fonts

And see if that fixes it ...

Hmmm.

It might be a PHP bug (in certain environments).

http://bugs.php.net/bug.php?id=6960

The full path fix they talk about won't work, because I already use the full path in graphlib.php

I know you're on a hosted server so upgrading PHP is not possible.

I'm not sure what you can do. sad

Perhaps someone else has an idea?
