Problem: The client is experiencing an issue where the credit card form on the checkout page does not appear correctly in the default language, although it appears fine in the sublanguage. The client questioned if WPML might be conflicting with any plugins. Solution: We have investigated the issue and determined that it is not related to WPML. It seems to be linked to the server environment or the payment methods used. We recommend the following steps to diagnose the issue further: 1. Temporarily deactivate all WPML plugins. 2. Ensure that your WordPress site language is set to English. 3. Visit the checkout page (/checkout/). 4. Check if the credit card form issue persists. If the form appears correctly with WPML plugins disabled, it should also work correctly once you reactivate WPML.
Please note that this solution might be outdated or not applicable to your specific case. If the problem persists, 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 needed, do not hesitate to open a new support ticket for further assistance.
