Performance

Problem:
The client experienced slow AJAX calls for adding and removing items from the cart on their WooCommerce site when the WPML String Translation plugin was active. The issue persisted even after deleting all string translations.

Solution:
We recommended the following troubleshooting steps:
1. Create a full site backup.
2. Update all outdated plugins and themes, especially WPML plugins.
3. Flush any cache memory.
4. Deactivate all plugins, including WPML ones.
5. Activate a default WordPress theme, then the parent theme.
6. Reactivate the WPML plugins, WooCommerce, and WooCommerce Multilingual & Multicurrency plugins.
7. Add products to the cart to check if the performance issue persists.
8. If resolved, reactivate the child theme and other plugins one by one to identify the problematic plugin.

The client found that the issue was caused by the 'woopayments' plugin, specifically its multi-currency option.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket.

Problem:
The client is experiencing slow performance when changing languages on their site using the WPML plugin. The first language change is particularly slow, affecting page speed scores and possibly user navigation.

Solution:
We recommend updating to the latest versions of WordPress, WPML plugins, and other themes and plugins. Initially, test with only WPML plugins active, then gradually activate other plugins one by one to identify when the performance starts degrading. This step will help determine if the issue is specifically with WPML or another factor.

Ensure that caching is enabled on the site, as it can significantly improve performance. The client is using W3 Total Cache, which should also be configured on the development site.

We also suggest consulting the performance improvement tips listed on our forum at https://wpml.org/forums/topic/how-can-i-improve-performance-of-a-slow-site/#post-15350474.

If these steps do not resolve the issue, or if the solution becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 at WPML support forum for further assistance.

Problema:
Si estás experimentando una carga lenta en tus sitios con el plugin WPML, es posible que no sea directamente un problema con WPML, sino con la configuración de tu servidor o con otros plugins.
Solución:
Te recomendamos seguir estos pasos para identificar y resolver el problema:
1. Incrementa el límite de memoria de WordPress a un mínimo de 512MB. Puedes hacerlo añadiendo el siguiente código en tu archivo wp-config.php, justo encima de la línea /* That's all, stop editing! Happy blogging. */:

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

2. Verifica el límite de memoria actual en WPML -> Soporte.
3. Si el problema persiste después de aumentar la memoria:
- Crea una copia de seguridad del sitio completo
- Actualiza cualquier plugin o tema desactualizado
- Borra cualquier caché existente
- Desactiva todos los plugins, incluyendo los de WPML
- Activa un tema por defecto de WordPress, como Twenty Twenty
- Reactiva los plugins de WPML
- Activa el tema y luego los demás plugins uno por uno, hasta identificar el causante de la lentitud.
Si después de seguir estos pasos el problema persiste o si la solución propuesta no es relevante debido a que está desactualizada o no se ajusta a tu caso, te recomendamos abrir un nuevo ticket de soporte. También es altamente recomendable que revises los problemas conocidos y verifiques que tienes instaladas las últimas versiones de los temas y plugins.
