Problem:
You are experiencing high CPU usage due to PHP warnings related to 'file_exists()' and 'realpath()' caused by open_basedir restrictions.
Solution:
If you're encountering these issues, we recommend checking if the REST API is enabled on your site, as it is essential for several WPML features. You can learn more about WPML's REST API dependencies here: https://wpml.org/documentation/support/rest-api-dependencies/
Please follow these steps:
1. Temporarily disable all non-WPML plugins.
2. Ensure that the REST API is enabled.
3. Test again with only WPML plugins active.
Always ensure to back up your database before making any changes.

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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