Problem: You are trying to translate Gutenberg templates (both archive and single) for your site and encountering a JSON error when attempting to create translations directly in the backend. Solution: We recommend not creating a different template for each language. Instead, use Translation Management to translate the template from your site's default language. Please follow this guide for detailed instructions: Translating sites that use full site editing.
If this solution does not resolve your issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should the problem persist, please do not hesitate to open a new support ticket for further assistance at WPML support forum.
