Error when retrieving message list

If you're getting Error when retrieving message list message, make sure you have mbstring extension available in your PHP setup.

One of the ways to check that is to create the following PHP script:

<?php

phpinfo();

Open it in web browser and search for mbstring in the output.

If the extension is not available, WebMail Lite 7 would still work fine with emails most of the time, but the extension is required if mailbox contains messages with invalid UTF-8 content.
