I am trying to:
Upgrade from version 1.83.

Instead, I got:
I manually installed the plugin however it doesn't upgrade the existing database and prompt for 'Run Upgrade Process'. When I click it, nothing happens.

Hi,

Thank you for contacting WPML support. If you performed the update in only one step it may be the reason for your issues. When updating from a really old version, you need to update the plugin in several steps.

Please make a full backup of your website (files and the database) before doing any of the following suggestions.

First, please do the following:
1. Go to WPML->Support.
2. Scroll down to the middle of the page and click the "troubleshooting" link.
3. In the "Clean up" section find the "Clear the cache in WPML" button. Click it.
4. Find the "Remove ghost entries from the translation tables" button. Click it.
5. Scroll down a bit and find the "Recreate ST DB cache tables" button. Click it.
6. Clear your site and server cache, if you have any.

---

If the issue still occurs and you have a backup of your site from before the update, at this point the easiest way would be to upload the backup and update WPML again, this time in several steps:
2.8 -> 2.9 -> 3.0 -> 3.1.8.1 -> 3.1.9.7 -> 3.2.7 -> 3.3 -> 3.3.3 -> 3.4.1 -> 3.5.3.1 -> 3.6.3 -> 3.7.1->3.8.2 -> 3.9 -> 4.0.1 -> 4.0.7

Please deactivate all other WPML plugins, update the core (step by step) and then update add-ons (you can update add-ons in one step using automatic updates when you are finished with updating the core file).

You can find older WPML versions at https://wpml.org/download/wpml-multilingual-cms/?section=changelog.

For each update step please do the following:
1. Go to https://wpml.org/download/wpml-multilingual-cms/?section=changelog.
2. Download WPML in the currently needed version (you can download all needed versions immediately, naturally).
3. Unpack the zip folder.
4. Log into your FTP.
5. Go to wp-content/plugins and delete the "sitepress-multilingual-cms" folder.
6. Upload the previously downloaded and unzipped folder.
7. Log into your WordPress admin panel.
8. Go to Plugins->Installed Plugins and activate WPML Multilingual CMS (if it's not activated already).
This step is really important, even if you know that the plugin will be activated. When you visit the admin panel, WPML performs actions needed to finish the update, e.g. the database schema will change, if there were any changes in the currently installed version. This is also the reason why you need to do the update in steps. We changed the database schema several times since 3.1.5 and it's important to have it upgraded step by step.

Check also the article about updating at https://wpml.org/faq/install-wpml/.

Hope that helps,
Ricardo
