Problem:
You are experiencing a performance issue with WPML where a GET query to check if the REST API is available is causing the Admin Panel to load very slowly. Despite increasing the WP memory limit to 512M, the issue persists.
Solution:
First, ensure that your WordPress memory limit meets the minimum requirements by adding the following code to your wp-config.php file:
1 | <br />define('WP_MEMORY_LIMIT', '512M');
|
You can verify the memory limit in WPML -> Support. If the performance issue continues, follow these steps:
1. Create a full site backup or a staging site.
2. Update any outdated plugins and themes.
3. Flush any existing cache.
4. Deactivate all plugins, including WPML ones, and activate a default WordPress theme like Twenty Twenty.
5. Reactivate the WPML plugins. If the issue resolves, reactivate your theme and other plugins one by one to identify the problematic one.
Regarding your specific questions:
1. Temporarily disabling the REST API check using
1 | add_filter('wpml_health_check_enabled', '__return_false');
|
can cause unintended issues with WPML functionality.
2. The long duration of the GET request is not due to WPML’s external server response time.
3. There is no way to cache or optimize this request within the WPML interface.
If these steps do not resolve your issue or if the solution becomes outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 necessary, please open a new support ticket at WPML support forum for further assistance.
