Problem:
The client was unable to translate certain buttons and headlines on their development site using WPML, suspecting an issue with custom XML configuration. The specific elements in question were created using WPBakery, and despite adding XML configuration for shortcode attributes, translations were not appearing.
Solution:
We advised the client to ensure their XML configuration was correctly set up for the specific shortcodes and attributes used in WPBakery. We provided guidance on creating and modifying the XML configuration file (https://wpml.org/documentation/support/language-configuration-files/). Additionally, we recommended translating URL-encoded shortcodes by following another guide (https://wpml.org/documentation/support/translating-urlencoded-shortcodes/). After reviewing the client's site directly and making adjustments to the XML, the translations were successfully updated.

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your specific case, we highly recommend checking related known issues (https://wpml.org/known-issues/), verifying the version of the permanent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. If problems persist, please do not hesitate to open a new support ticket at WPML support forum.
