If you have a Wiris Quizzes service running in your server, naturally you'll want to configure the Moodle modules to use it.

[WIRIS QUIZZES] server components

Configuring WIRIS plugin

Edit the file

<moodle-root-folder>/lib/editor/tinymce/tiny_mce/<tiny_mce-version>/plugins/tiny_mce_wiris/configuration.ini

Change the following key with the value of your server:

wiriscascodebase = http://<your-server-domain>/wiris/wiris-codebase

Eventually you might also need to change: wiriscasarchive, wiriscasclass.
