    Sarendar - On line 57 of the lib.php try changing http to https. When I get a chance I will update the code so it works on both http and https servers. Thanks for trying my plugin.

    Good day, our Chemistry department is desperate for this plugin, or something similar. We're on Moodle 3.5 and cannot run the current versions. Are there any plans for updates, or can anyone make suggestions for alternative plugins/software.
