  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.

  Does the lab allow for Python 3. I see the screenshots show C, Java etc, but no Python 3.

  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.

  Hi Prof JC,
  Thank you for VPL - it is a very significant achievement and very important to those of us trying to teach remotely during the pandemic.
  I have added a custom vpl_evaluate.sh to a VPL activity, that generates a vpl_execute that checks the student source for certain statements using grep. This works and correctly gives the work a grade. However, I want the source to be syntax checked and the output checked in the normal way. The evaluate in VPL is not running the base vpl_evaluate.sh for python 3 to check the code and vpl_evaluate.cases. How do I best achieve this please?

  I managed to get this working by copying in all the needed vpl_ files into a base VPL and then deriving from that. Not sure if that's the best way, as it means I have to potentially update after every upgrade.
