Problem: The client is using the Testimonial Showcase plugin and is unable to see the original Dutch text when trying to translate testimonials using WPML. The issue does not occur with regular pages or posts. Solution: 1. We recommend using the String Translation module of WPML to translate the testimonials. For guidance on how to use this module, please visit String Translation documentation. 2. If the issue persists, it may be necessary to provide temporary access (WP-Admin and FTP) to a test site where the problem has been replicated so we can further investigate and make necessary configuration changes. Before providing access, ensure to back up your site using a plugin like UpdraftPlus, available at UpdraftPlus plugin.
If this solution does not resolve your issue or seems outdated, we highly recommend checking related known issues at known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please do not hesitate to open a new support ticket for further assistance at WPML support forum.
