This thread is resolved. Here is a description of the problem and solution.

Problem:
update from old version

Solution:

1. Different versions of WPML can be downloaded from this link here, under your WPML.org account - https://wpml.org/download/wpml-multilingual-cms/?section=changelog

2. Please make sure that you first create a full website backup so that you are safe no matter what happens.

3. The oldest version you are able to download from that link is "3.8.3". After that, I recommend that you update to each new major version (3.9, 4.0, 4.1, 4.2 and 4.3).

You can also try to create a full website backup first and then update to the latest version and see what happens - it there's gonna be serious errors and not simple notifications, then please update gradually.

Tell us what you are trying to do?
Currently WPML version 3.2.2 is on this site. I have updated WP and other plugins and now I need to update WPML as well.

Is there any documentation that you are following?
https://wpml.org/errata/updating-wpml-in-a-secure-way-from-a-very-old-version/

it says I need to upgrade in major steps, so I cannot just download the latest version and update. Which versions do I need to upgrade to first? And where can I get those versions?

Is there a similar example that we can see?

What is the link to your site?
it is still on my local machine

Hi Hans.

That is great and sounds like a good plan. Please don't forget to create a backup before doing anything else.

If things are going out alright, can you also please mark this ticket as resolved?

Please let me know.

Hi Mihai

everything worked fine on my local machine. I had to create a key in my WPML account and did so for houseoflifeabydos.local.

Now I have put the site on the live location, houseoflifeabydos.com but I cannot activate WPML, it crashes the site. Both local and live site are on php 7.2.
By enabling the plugin I had not yet had the possibility to update the WPML key, it crashes the site upon activating.

I enabled debugging and receive the following:

Fatal error: Uncaught Error: Call to undefined method stdClass::is_enabled() in /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-settings.php:346 Stack trace: #0 /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-inline-styles.php(274): WPML_LS_Settings->get_active_slots() #1 /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-admin-ui.php(105): WPML_LS_Inline_Styles->admin_output() #2 /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-includes/class-wp-hook.php(288): WPML_LS_Admin_UI->admin_head_action('') #3 /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(NULL, Array) #4 /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #5 /mnt/web020/e0/15/53905115/htdocs/WordPress_01/w in /mnt/web020/e0/15/53905115/htdocs/WordPress_01/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-settings.php on line 346

can you please help?
I really do not know what to do now

Hi.

That can happen for multiple reasons.

1. Please make sure that the WPML minimum requirements are met (https://wpml.org/home/minimum-requirements/)

2. Please disable all the non-WPML plugins and see if the issue is still happening.

3. If that still happens, please try this, too: delete the WPML plugin and then try to reinstall it after you download it from your WPML.org account.

Also, I don't know what process you followed for migrating the site from local to production, but our recommendation is to use a plugin like "Duplicator" (https://wordpress.org/plugins/duplicator/)

Documentation can be found here: hidden link

Here is a small tutorial on how to use Duplicator:

Please let me know how that goes.

Kind regards,
Mihai

Hi, Mihai,

I have checked the requirements: all ok.
I have disabled all other plugins: same issue.
I have reinstalled the latest version of WPML. Same issue.

I have migrated the site not using Duplicator but a similar tool, Ithemes Backupbuddy / importbuddy.

Based on the error, I have found this post: https://wpml.org/forums/topic/fatal-error-when-activating-wpml-multilingual-cms-on-digital-ocean/

so I created a clean WordPress install, installed WPML and copied content of said database table over to the site.

Now it works.

thanks
