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

Finally, after very long (and complex) development, ICanLocalize clients can upgrade WPML to its current version and continue to enjoy a streamlined translation workflow.

Problem :

It wasn't possible to use ICanLocalize translation service with the WPML greater than 3.2, if you have done some translation through the service already.

Solution :

Read carefully this article :

Just to summarize about how to Update to the Current WPML Version :

1. Take a backup 2. Deactivate and remove an old version of WPML plugins 3. Download the newest ones from here : 4. Install and activate the latest WPML plugins (WPML 3.2.7, WPML ST 2.2.6, WPML TM 2.0.5) 5. Download plugin "Migrate ICanLocalize Translation to WPML 3.2" : 6. Install and activate it. 7. Go to the new menu that the plugin created for the migration process WPML->Migrate ICanLocalize Translation to WPML 3.2 8. You will see two buttons. First, click to migrate the account to WPML 3.2. This runs almost instantly. Then, click to migrate the jobs. 9. You no longer need the migration plugin. Go to Plugins and deactivate it.

If there are any problems in this migration process (there should not be), the migration plugin will report them on the screen. Create a new ticket in WPML technical support forum, copy what you see and paste in the forum thread. Be sure to explain what you are doing and what you are seeing.

@emmanuel, I have made the downgrade. The other extensions I had to deactivate, you also need to change them to the latest official versions (not use the beta versions).

I am looking for WPML string translation plugin v2.0.3 as the latest version has problem with the Realty theme and the maker of the theme suggested to get an older version of the plugin.

Kind regards,

I upgraded to 3.2 RC2 to see whether issues of disappearing media were fixed (another story), but they were not. When I tried to deactivate all the plugins, I eventually got: "Fatal error: Call to a member function get_backtrace() on a non-object in /home/kastler/www/wp/wp-content/plugins/sitepress-multilingual-cms/inc/query-filtering/wpml-query-filter.class.php on line 28".

I want to either downgrade, or just remove this version. I have not translated anything at this point, so nothing to lose.

Thank you

@elizabeth, I am strongly recommend do not use the outdated plugins the latest official version of String Translation is 2.1.3. The version you are asking, have been released 2 year ago, I am completely sure that it will not work fine with the current versions of WPML, WP.
The theme author gave you wrong suggestion, I believe he needs test his theme for compatibility. You can open a new ticket and describe your issue there, if it is compatibility, then our team will send request to the author asking him to make his theme compatible with WPML, but it depends on him.
You also can invite him join to our Go Global program :

@curtis, if you have nothing to lose, try to deactivate all addons and then go WPML >> Support > Troubleshooting and click "Reset all language data and deactivate WPML". After, just install the latest official versions and configure WPML again.

@paolov-4, Do you want to make a downgrade ? I want to remind that here I can help you to make a downgrade, but not solve the problem that you have. If you have still the issue after the downgrade then you need back to your original reported ticket and continue with the support that is assisting you.

I'm getting the same issue that I can't use WPML 3.2 RC due to the icanlocaliaze configuration.

I'm not using Icanlocaliaze and I would like to disable it, as I need the new version due to one bugfix in it.

Could you guide me how to disable to functionality which does not allow me to use RC?

(We can handle manual database updates).
