solso on "[Plugin: Tribulant Newsletters] Conflict / Error 500 when changing WPML settings"

Thanks again for your reply.

Pls find here below all the details including debug info :

Thanks for your reply.

About the details :
- WP 4.5.2
- TRIBULANT newsletter newsletters-lite.4.6.1.2 (i tried also previous version, same result. When all was fine in previous WP version)
- WPML 3.3.8 and string translation 2.3.7.

This issue happens when we tu "string translation settings" to "Auto-register strings only when logged in as an administrator". Then we get an inteal error server 500.

We tried this also on a fresh install with just WP + TRIBULANT + WPML, same issue.
HTTP ERROR 500 in the admin section. Front is still available.
