Problem: The client installed WPML using the Airtifact theme and Learnpress. Previously, Google Translate was used, and there was a concern about a potential conflict even after its removal. The language selector was redirecting to a blank page when switching languages. Solution: We suggested that the Airtifact theme is not compatible with WPML. To confirm if this is causing the issue, we recommended switching to a default theme like Twenty Twenty-one and checking if the problem persists. If the issue is resolved with the default theme, the next steps involve: 1. Disabling all plugins except for WPML CMS. 2. Temporarily switching to a default WordPress theme like Twenty Twenty-one. If the problem disappears, reactivate the plugins one by one to identify which one causes an interaction issue. If the problem still persists, we advised checking the WordPress error log for more detailed error information.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend opening a new support ticket. Please also check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. For further assistance, you can contact us through the WPML support forum.
