Problem: The client's website was experiencing slow performance due to a high number of database queries generated by WPML when handling ACF nested repeater fields in posts. The client wanted to minimize these queries by ensuring WPML does not translate these fields.
Solution: We recommended setting the custom post types (CPTs) like 'Songs' and 'Guided Lessons' to non-translatable in WPML settings to prevent WPML from processing these fields. Additionally, to address the high number of queries caused by the Search & Filter plugin and taxonomy labels registered by CPT UI, we suggested: 1. Adding the following code to the theme's functions.php file to bypass WPML’s term ID adjustment:
2. Replacing CPT UI’s dynamic taxonomy registration with static code by copying the code from CPT UI → Tools → Get Code and adding it to a custom plugin.
These changes aimed to reduce the load caused by unnecessary translations and database queries. We advised testing these changes on a staging site first and ensuring a full backup before applying them to production.
If this solution does not apply to your case, or if it seems outdated, we recommend opening a new support ticket. We also 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.
