I am trying to:
Activate WPML Multilingual CMS after installing the plugin in a multisite environment.
Link to a page where the issue can be seen:

I expected to see:

Instead, I got: A message "Fatal error: Uncaught Error: Call to undefined function WPML\Container\wpml_collect() in ......... wp-content/plugins/sitepress-multilingual-cms/classes/container/class-wpml-container.php:38 Stack trace: #0 ....wp-content/plugins/sitepress-multilingual-cms/classes/container/functions.php(35): WPML\Container\Container::share(Array) #1.... plugin_sandbox_scrape('sitepress-multi...') #4 {main} thrown in ......./wp-content/plugins/sitepress-multilingual-cms/classes/container/class-wpml-container.php on line 38

Thank you for contacting WPML support.

I kindly ask you to visit this link and follow the steps described:

If the issue persists then I would like to ask you to follow this steps in order to isolate the cause of the issue:
- Back up your site first before making any change, this is for security reasons.
- Flush any cache memory that might appear.
- Deactivate all the plugins.
- Switch for a moment to a WordPress default theme like Twenty Seventeen.
- Try to activate WPML.
- If the issue is gone, activate one by one to see with which one there is an interaction issue.

Could you tell me the result of this steps?

Kind regards,

FYI: I have the same issue. At my site, is was the "WooCommerce PDF Invoices & Packing Slips Professional"-Plugin from Ewout Fernhout (V2.2.15), which caused the issue.
