I apoologise for not contacting you sooner. I've been working on other things and I haven't had much time.
As you already know, I'm quite new (and not really good) at Moodle. So, could you please tell me how to access and install the updated scripts?
Everytime I install a new program in Moodle, a message about not being advisable to set up the PHP display_errors. I don't know how to do that and even if I do, will that configuration change make the programs installed work?
Thanks for ALL your help.
