[Resolvido] Updated plugins and getting errors

Background of the issue:
I have updated the plugins on my site link oculto and encountered issues.

Symptoms:
I am getting errors after updating the plugins.

After the plguins updated I got this error:

2025/03/31 20:00:58 [error] 2130720#2130720: *40117 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to undefined function icl_register_string() in /var/www/anahatatantra.com/wp-content/mods/sergio-mailerlite-widget/index.php:19

Then I disabled that plugin, that was working fine since years!!

After I disabled it now I have these messages in wp-admin:
WPML Update is Incomplete
You are running updated woocommerce-multilingual, wpml-media-translation and wpml-string-translation, but the following components are not updated:

sitepress-multilingual-cms (required version: 4.7.0)
Your site will not work as it should in this configuration Please update all components which you are using. For WPML components you can receive updates from your WPML.org account or automatically, after you register WPML.

WooCommerce Multilingual & Multicurrency is enabled but not effective. It requires WPML String Translation in order to work.

WPML String Translation is enabled but not effective, because WPML is outdated. Please update WPML first.

But there are no updates, and the plugins are on.

Questions:
How to fix this issue?
in /wp-admin/update-core.php I get "Your plugins are all up to date."

What to do now?
