Problem:
If you're experiencing a fatal error when activating WPML, specifically an error related to 'call_user_func_array()' and 'WPML_TM_ICL20_Migration_Notices::build_migration_required()', and this persists even after deactivating all plugins and changing the theme, we have a solution.
Solution:
1. Ensure you are using the latest version of WPML. You can check and download the latest version from here.
2. Navigate to the file located at:

wp-content/plugins/sitepress-multilingual-cms/classes/ICL-20-migration/ui/class-wpml-tm-icl20-migration-notices.php

and go to line 169.
3. Change "private" to "public" on line 169 so it reads:

public function build_migration_required() {

4. Log in to your site, activate the WPML plugin, and complete the setup process.
5. Go to WPML → Translation Management → Translators and deactivate the old translation service.
6. Navigate to WPML → Support → Troubleshooting and perform the following actions:

• Select "Reset professional translation state."
• If there are no translations available, choose "Reset and deactivate WPML."

After completing these steps, you should be able to activate WPML and set it up without encountering any errors.
