Problem: The client is experiencing significant slowdowns in the WordPress admin area due to WPML-related queries, particularly around wp_icl_mo_files_domains and wp_options autoload rows like 'wpml_dependencies:needs_validation'. Despite previous cleanup efforts, heavy queries are still repeating on almost every admin page load. Solution: 1. Clean up unused MO files and domains by navigating to WPML → Theme and plugins localization and performing a scan of the theme and plugins for strings. After scanning, remove unnecessary files. 2. If performance issues persist, create a staging site to safely test changes without affecting the live site. Use the WP Staging plugin or ask the hosting provider for assistance. 3. Update WPML to the latest version via Plugins -> Add new -> Commercial tab and check if the issue persists. 4. Disable all plugins except WPML and switch to a default WordPress theme to isolate the issue. Reactivate plugins and themes one by one to identify any specific conflicts.
If these steps do not resolve the issue or if the solution seems outdated or irrelevant, please visit our known issues page, verify the version of the permanent fix, and ensure you have installed the latest versions of themes and plugins.

Problem: The client reported slow page generation times in the admin panel, particularly when using the VikBooking plugin or general admin pages. They noted significant memory usage and load on WPML-related calls via Query Monitor, despite having Redis Object Cache and WP Rocket active. The client also inquired about integrating VikBooking with WPML for multilingual support, including translating booking texts and emails.
Solution: We addressed the performance issues by suggesting the client enable WordPress's debug mode to identify specific errors causing the slowdown. Instructions were provided to modify the
wp-config.php
file to enable detailed logging. For the integration of VikBooking with WPML, we clarified that VikBooking is not officially compatible with WPML. We provided links to developer guides on achieving WPML compatibility and a list of officially compatible booking plugins as alternatives. Additionally, we offered a sandbox site for testing VikBooking with WPML.
