If your Complianz cookie banner or legal documents always display in the same language regardless of which language your visitor is using — for example, always showing Polish even when the site is set to English — this article walks you through the most common causes and how to fix them.
Step 1: Verify your WordPress site language
Go to Settings > General and confirm the site language is set correctly for your WordPress environment. Complianz uses this setting as the default language for the banner and legal documents.
Step 2: Reset the banner after changing language
This step is easy to miss. After changing the WordPress backend language, you need to manually reset the banner for the changes to take effect. Go to:
Consent Banner > General > Reset
Without this reset, the banner will continue to display the previously generated version in the old language.
Step 3: Update your translation files
Go to Dashboard > Tools > Translations and click "Check Now" to refresh all language files.
Step 4: Check your multilingual plugin setup
Are you using a translation plugin? If so, which one? The setup steps vary depending on the plugin. Follow the guide that matches your setup:
- Polylang: https://complianz.io/translate-legal-documents-to-multiple-languages-with-polylang/
- TranslatePress: https://complianz.io/translate-legal-documents-to-multiple-languages-with-translatepress/
- WPML: https://complianz.io/translate-legal-documents-to-multiple-languages-with-wpml/
If you are not using a multilingual plugin and are still seeing the wrong language, let us know and we can help narrow down the cause.
Step 5: Clear cache
After making any of the above changes, clear both your site cache and your browser cache before checking the result.
Step 6: Check for plugin conflicts (Premium users)
If you are using Complianz Premium, make sure the free version of the plugin is fully deactivated and deleted. Running both versions simultaneously can cause unexpected behavior, including language issues.
Still seeing the wrong language?
If the issue persists after following these steps, please share the following details so we can investigate further:
- Which translation plugin you are using (Polylang, WPML, TranslatePress, or none)
- Whether the issue affects the cookie banner, the legal documents, or both
- Any error messages you are seeing
The most common remaining cause is untranslated banner strings or HTML content inside the banner itself, which requires completing the string translation step in your multilingual plugin. The guides linked in Step 4 cover this in detail.
