Resolución de incidencia con WPML de Wordpress

Requiero de un experto en WP con conocimientos de WPML para realizar dos acciones sobre un cliente en WP 1 - Resolver un problema por el que varias de las páginas de la web no cargan (whitescreen), debido a algún conflicto de WPML, ya que desde la instalación del plugin, la web ha presentado un comportamiento extraño como el que relato. 2 - Actualizar el plugin WPML y el core de WP a la version 5 Este sería un servicio urgente, por lo que agradecería adjuntar fecha de entrega y la garantía de que todo el sistema queda funcionando perfectamente. Gracias! _____ After installing and setting WPML on this customer, it has shown an strange behaviour, showing a blank page on some of the pages. This is a common WPML issue. This customer has SPANISH and ENGLISH version, and it is created under AVADA constructor. This is an urgent service as the customer is down while this happens. I need you to, please, solve this problem finally, as well as update WPML and Wordpress to 5.0 Please, I'd also need a deadline for this fix (as this is an urgent need for the customer) and the warranty that the whole system would keep working as before, but with this issue solved and everything updated. I await the estimate and deadline ASAP, very grateful for your attention.
