Problem:
If you're experiencing a 503 error in the backend of your site that appears briefly and then disappears upon refreshing, it might be due to a conflict between WooCommerce and WPML or a memory limit issue.
Solution:
We recommend following these steps:
1. Create a Full Backup: Ensure you have a complete backup of your website (files and database).
2. Increase PHP Memory Limit: Add the following to your wp-config.php file:

define('WP_MEMORY_LIMIT', '256M');

define('WP_MAX_MEMORY_LIMIT', '512M');

3. Check for Plugin Conflicts: Deactivate all plugins except WooCommerce, WPML, and Elementor, then reactivate them one by one to identify the conflicting plugin.
4. Troubleshooting WPML: Navigate to WPML > Support > Troubleshooting and perform:
- Fix WPML Table collation
- Set Language information
- Clear WPML Cache
5. Review and Update Plugins: Ensure all plugins, especially WooCommerce and WPML, are updated. Go to Plugins > Add new > Commercial > click "check for updates" > and update all the outdated plugins.

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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 the problem persists, please open a new support ticket at WPML support forum.
