I have a conflict with the JSON Content Importer Pro plugin, which also uses the Twig engine. Deactivating only the Views module in AIO fixes the error screen, but obviously this is not a solution.
Which version of Twig does Meta Box use? I can't find it in the changelog.
In JSON Content Importer Pro, I can choose one of several Twig versions (for example 3.3.2, 3 or older) but none of them works with Views.
