Problem:
After upgrading from Divi 4 to Divi 5, the client is experiencing multiple issues on their site, including changes in page layouts and background colors, and some pages not displaying at all.
Solution:
We recommended the client to check if the issue persists with WPML deactivated to determine if it's a WPML-related issue or a problem with Divi itself. We advised editing the affected pages to check if the layout settings such as 'Fullwidth' have been altered. Additionally, we highlighted an ongoing compatibility issue between Divi 5 and WPML, as Divi 5 is still in its alpha phase and undergoing updates. We provided a link to our errata page for more details and possible workarounds: https://wpml.org/errata/divi-5-wpml-compatibility-while-new-features-are-being-released/

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 further assistance is needed, please open a new support ticket at WPML support forum.
