Now, we can try to reproduce the issue once again.
We should now be able to locate the debug log in: /wp-content/debug.log
Paste the content (if any) on a site like pastebin.com and then share the link with us (only you and us will see the URL you are sharing, it is automatically hidden for anyone else).
Does the same issue occur when you try the following steps?
1. Download fresh copies of WPML from https://wpml.org/account/downloads/.
2. Disable the WPML plugins.
3. Delete the plugins (note that the settings and translations will be saved in the database and will not be deleted).
4. Upload the freshly downloaded WPML plugins by going to Plugins -> Add New -> Upload Plugin.
5. Activate the plugins.
Please let me know how it goes. Before making any changes, make sure to back up your database first.

As soon I try reactivate string translation i immiedialty get again te error if i try acces wpml. so its comming from the wpml string translation but we need it.
