function in WordPress are not being applied to images in translated versions of their website, despite working in the original language. Solution: We recommend running the "Regenerate Thumbnails" plugin for each language version of the site where the custom image sizes are not applying correctly. This action should help in applying the custom sizes across all languages. If this solution does not resolve the issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If the problem persists, please do not hesitate to open a new support ticket with us for further assistance at WPML support forum.
