When users try to download their invoice, they get this message (in debug mode):
Fatal error: Call to undefined function mb_internal_encoding() in /var/www/html/xxx/wp-content/plugins/event-espresso-core-reg/core/third_party_libs/dompdf/dompdf_config.inc.php on line 329
That error usually means that the your server doesn’t have the mbstring extension installed, or it is not active.
I would recommend contacting your host to have them enabled that module on your site, or if you have access to the server (and are comfortable doing so) you can do this yourself within the php.ini file, look for ;extension=php_mbstring.dll and remove the semi-colon from the begging.
You may need to restart Apache once this is enabled.
