Install and update

Problem:
I cannot remove the «WPML plugin cannot connect to wpml.org» problem even when I am deleting the old license key and getting a new one.

Solution:
Check the following:

• the values of the home and siteurl are correct in the database (on the wp_options table) page;
• generate a new site key for your website in https://wpml.org/account/sites/;
• delete the wpml_notices and wp_installer_settings from the database (from the wp_options table).

Problem:

There is an invalid key error when I want to register WPML. I already added the key on wpml.org.

Solution:

Such an issue is usually related to the usage of an old version of the WPML plugin. If the current version of the plugin is older than 4.4 you need to use the manual update method below:

- Create a backup of your website. You can use backup tools from WordPress: https://wordpress.org/plugins/tags/backup/

- Make sure you are signed in wpml.org.

- Go to https://wpml.org/account/downloads/

- Download the latest version of the WPML and its add-ons.

- Install them manually on your website using the method below:
