Problem: When using WPML 4.8 together with a page builder (e.g., Elementor), attempting to open the Translation Editor may result in a PHP fatal error similar to:
PHP Fatal error: Uncaught TypeError: array_merge(): Argument #1 must be of type array, null given
in .../sitepress-multilingual-cms/classes/media-translation/AddMediaDataToTranslationPackage.php:82
This occurs when the page includes an image that lacks metadata (i.e., no title, caption, description, or alt text). Solution: We published an errata for this issue. The issue was fixed in WPML 4.8.1, which can be downloaded at Plugins > Add new on the "Commercial" tab or from https://wpml.org/account/downloads/.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. If problems persist, please open a new support ticket at WPML support forum.
