Hosts & Servers

This guide serves as reference for any host or server-specific information we gather. If you have experience hosting WordPress with a particular host, stack, or service (AWS, Azure, etc.) please add that information here so it can be shared.

WordPress VIP #

Automattic offers a paid service called WordPress VIP for enterprise customers. To get Timber to play nice with their stack, we need to disable functionality related to caching and writes to the filesystem:

functions.php

add_filter('timber/cache/mode', function () {
    return 'none';
});

add_filter('timber/allow_fs_write', '__return_false');

This means you will not be able to use on-the-fly image resizing through Timber. Don't despair! You can set custom image sizes for WordPress to use:

functions.php

add_image_size('my_custom_size', 220, 220, ['left', 'top']);

single.twig

<img src="{{ post.thumbnail.src('my_custom_size') }}" alt="{{ post.thumbnail.alt() }}">

WordPress VIP has its own caching mechanisms. So when we disable caching, we're only disabling Timber and Twig's caching — not other layers that WP VIP applies.
