Try adding the following to your config.php:

// Basemap provider (CARTO now watermarks unkeyed tiles and 26.8 has no key support) $config['frontpage']['map']['tiles'] = 'esri-worldgraycanvas';

then:

systemctl reload php-fpm

Thanks

Hi,

The map tile provider, Carto, changed their system for free map tile usage.

In the latest rolling versions we switched to another default tile provider, but also added the ability to add an API key for carto and other providers.

This'll be in stable at some point in the future, but we've had a lot of large changes recently so it's not a great time to merge them into stable yet.

Thanks, adam.
