    Yes, you must use html, css and js as file extensions. If you allow using enough resources in your jail server, you will see the results in a browser at the jail server.

    Hi Juan Carlos
    I hope everything is fine with you.
    Thank you to help the community with your excellent VPL tool! I have been intensively using it since 2014.
    Some time ago I reached a small bug, when using "Reports > Logs": the column "Event name" related to VPL has its URL broked.
    E.g. to the event "mod_vpl: submission viewed" I got the URL = https://saw.atp.usp.brmod/vpl/forms/submissionview.php?id=18095
    Today I examined it in detail and found its source: in VPL file '/mod/vpl/classes/event/base.php' it is sufficient to add
    a slash "/" at the beginning of the first parameter 'mod/vpl/' in its line 38, i.e.,
    replacing "return new \moodle_url( 'mod/vpl/' . $script, $parms );"
    by "return new \moodle_url('/mod/vpl/' . $script, $parms );"
    the problem is solved.
    Best regards

    Dear Charles Talathoti,
    The installation of Moodle says that the PHP extension xmlrpc "should be installed and enabled for best results". VPL requires the xmlrpc extension and you must install it on your Moodle server. For example, for Ubuntu, you must run "sudo apt-get install php-xmlrpc" and restart the web service.
    Best regards,
    Juan Carlos.

    Dear Prof. Carlos
    We have recently updated to Moodle 3.9 version. Also we have installed VPL on it. While clicking on run button, error message popped up "PHP cURL Required". Can you suggest possible solution of it.

    Best Regards
    Ashish

    Dear Ashish Phophalia,
    Moodle 3.9 at administration environment checks indicate that:

    php_extension curl must be installed and enabled

    Contact to your sysadmin to install php-curl.

    Best regards,
    Juan Carlos.

    I cannot write to files in either Python or Java. Reading from files work but writing to files do not work. Do you have any advice?

    Dear Tapu Ahmed,
    notice that the execution is done by a temporal user that can write files at its home directory on Linux (the running program's current directory). Never user absolute path to file, the better way is to use relative path names.
    Bets regards,
    Juan Carlos.
