Problem: The client experienced an issue where the site's text became unreadable with scrambled letters and charset changes after deleting previous administrators and transferring their settings. The issue was accompanied by PHP errors related to charset support in the console. Solution: We suggested checking if the problem persists when WPML is deactivated to determine if it's related to WPML or a broader database configuration issue. Additionally, we recommended changing the character encoding and collation of the database tables. Here are the steps we advised: 1. Temporarily deactivate WPML to see if the issue still occurs. 2. Follow the documentation to change the character encoding and collation of your database tables: https://wpml.org/faq/texts-showing-as/ If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your current setup, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the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 for further assistance.
