Problem: After updating WPML plugins, both language widgets are displayed in the same language, and string translation does not reflect the translated widget. Solution: 1. Check if the issue persists with the WordPress default theme and regular widgets. 2. This is a known issue with custom HTML widgets being displayed in all languages. You can find a temporary workaround here: https://wpml.org/errata/wordpressp-5-8-custom-html-widgets-are-displayed-in-all-languages/ 3. The issue will be permanently fixed in WPML version 4.7.5. You can download this version from your account when available: https://wpml.org/account/downloads/
If this solution does not apply to your case, or if it seems outdated, we recommend opening a new support ticket. We also 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.
