[Resolved] web site is very slow after installing wpml

Problem:
After installing WPML to translate their website, the client's site became very slow. The client wants to know why and how to resolve the performance issue.
Solution:
1. Increase the WP Memory Limit to at least 128MB, ideally to 256MB for optimal performance. Open the

wp-config.php

file and add the following line just before the comment that says '// That's all, stop editing! Happy blogging.':

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

2. After updating the memory limit, clear any caches (plugin, browser, and server-side if available), then check your site speed again.
3. If the site remains slow, deactivate all plugins except WPML and its add-ons to check for plugin conflicts. Reactivate them one by one to identify any specific plugin causing slowdowns.
4. Enable object caching and configure a caching plugin like W3 Total Cache for improved performance.

If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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. If the problem persists, please open a new support ticket for further assistance.
