Not WPML issue

Problem:
The client was experiencing issues with WPML not functioning correctly due to the WordPress REST API not responding as expected. Additionally, there was a compatibility issue with the Breakdance plugin, which was not working with WPML.
Solution:
1. We recommended checking if any security or firewall plugins were blocking REST API requests, or if the REST API had been disabled via the rest_enabled filter.
2. We suggested ensuring that server configurations or custom rewrite rules were not interfering with WordPress routing.
3. We advised the client to flush any existing cache memory that might be causing issues.
4. We increased the WordPress memory limit by adding the following code to the wp-config.php file:

/* Memory Limit */<br />define('WP_MEMORY_LIMIT', '512M');

5. We confirmed that the Breakdance plugin is not compatible with WPML, as verified on https://wpml.org/plugin/breakdance/.

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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.
