Broken link
Hi!

I was trying to install the GeoGebra extension but the link to http://www.geogebra.org/webstart/unsigned/unpacked/ is broken. I got: Error 403. Denied access

How can I download that files? Thanks in advance... Helder 18:39, 6 March 2010 (UTC)


 * I have no problem with downloading e.g. geogebra.jar from http://www.geogebra.org/webstart/unsigned/unpacked/
 * Maybe trouble with protection software? At my school we have problems with dansguardian. See also personal mail.

Avoiding errors in error log
From apache error log
 * [Thu Mar 11 20:18:45 2010] [error] [client 10.41.3.15] PHP Notice: Undefined index:  substimage in /var/www/html/cats/extensions/GeoGebra/GeoGebra.php on line 81, referer: ...

This can be avoided by replacing these three lines
 * $imgBinary = htmlspecialchars(strip_tags($args['substimage']));
 * $useSignedJar = $args['usesignedjar'];
 * $useLocalJar = $args['uselocaljar'];

with something like
 * $imgBinary = isset($args['substimage']) ? htmlspecialchars(strip_tags($args['substimage'])) : '' ;
 * $useSignedJar = isset($args['usesignedjar']) ? $args['usesignedjar'] : '' ;
 * $useLocalJar = isset($args['uselocaljar']) ? $args['uselocaljar'] : '' ;
