I need the Tex Filter in Moodle to work





infinisa
Hello Folks

I should like to have the Tex filter (in Moodle) working so as to display maths expressions using LaTex correctly.

Unfortunately, when I run the test script http://infinisa.frih.net/moodle/filter/tex/texdebug.php
I get the following error messages which means the test failed due to security restrictions:

Warning: escapeshellarg() has been disabled for security reasons in /home/infinisa/domains/infinisa.frih.net/public_html/moodle/filter/tex/texdebug.php on line 108

I should be grateful if you could lift the restrictions so that the Tex filter in Moodle will work.

Thanks.

sorry won't happen, stuff like 'shell_exec()' will never be enabled. You'll have to find some other way to do the same, because I don't think this software can be used on frihost.
