This thread is resolved. Here is a description of the problem and solution.
Problem:
If you're trying to enable multicurrency options on your site using WPML and find that all payment methods disappear when multicurrency is turned on, this might be due to not using the latest version of the WPML plugin and its add-ons.
Solution:
We recommend that you first update your WPML plugin and all related add-ons to the latest version, which is currently 4.7.0. This update includes the latest bug fixes and improvements that might resolve your issue. You can check the latest released versions and find update instructions on the WPML FAQ page. If updates are not visible, you may need to click the 'Check for updates' button in the Plugins → Add New Plugin → Commercial tab. Remember to backup your database before proceeding with any updates.
If updating does not resolve the issue or if this solution becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 open a new support ticket with us.
