Can you please elaborate on where you experience slowness on your site?
Is it on backend or frontend pages?
Please send us some example links to where you experience the slowness on your site.
To investigate this problem, please share with us WordPress's debug log (not WPML debug information). Please check this page for instructions.
To enable it, open your wp-config.php file and look for
define('WP_DEBUG', false);
Change it to:
define('WP_DEBUG', true);
// Enable Debug logging to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
// Disable display of errors and warnings
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);
After this, repeat the action that causes the problem on your site--visit a page that loads slowly. In this case, the errors will be saved to a debug.log log file inside the /wp-content/ directory. Then please share the errors with us. If the debug.log was already active, please only share the error you encountered during your test to keep the log concise and avoid unrelated errors.
Additionally, please refer to this guide on using the Query Monitor plugin to identify any slow queries that may be related to WPML, and share your findings with us.
