Problem: In a WordPress Multisite environment with subdirectories, WPML is installed and network-activated, but the WPML database tables (e.g., icl_strings) are not being created for sub-sites, leading to database errors indicating missing tables. Solution: If you're experiencing this issue, we recommend the following steps: 1. Go to WPML → Settings → Translation Editor. 2. Select Advanced Translation Editor. 3. Save the settings. After enabling the Advanced Translation Editor, the necessary database tables should be created, resolving the database errors.
Please note that this solution might be outdated or not applicable to your specific case.

If necessary, please open a new support ticket for further assistance.
