How to enable the intl extension


The intl extension is enabled by default on PHP versions above 7.2. If you're noticing any errors on your site related to this extension, please Contact Support for further assistance.

If your site is still running PHP 5.6, you must enable this extension manually by making a small addition to your phprc file.

It's not possible to enable this if your site is running PHP 7.0 on a server running Ubuntu Bionic. Please note that PHP 7.0 has already been EOL'd by, so it's highly recommended that you use a newer version as this will soon be removed from DreamHost servers.
