lonnekev	Background of the issue: I've installed WPML on my website hidden link, and I'm trying to resolve performance issues that have arisen since the installation. Symptoms: The website has become extremely slow and unresponsive after installing WPML. Disabling WPML restores normal performance, but deactivating other plugins or switching to a default theme does not help. See the attached images. Questions: How can I resolve the performance issues caused by WPML? Are there specific settings in WPML that could be affecting site speed?

lonnekev	It can be seen here for example: hidden link But the load times are bad both on the frontend and also the CMS itself. The updates didn't help resolve the issue.

Carlos Rojas Supporter Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+01:00)	Thank you for your authorization. Before I create a copy of the site, could you update all outdated functionalities that appear in this link: hidden link and then double-check if the performance issue disappeared?

lonnekev	I've updated everything. The code profiler plugin is not familiar to me (I assume you've installed it), but I can't update it. The Smush Pro plugin I can't update because the license only works on the main domain and not the staging domain. I've updated it on the live site as well and it doesn't resolve the issue. Updating the other plugins also didn't resolve the issue.
