[Resolved] Admin pane crashes when I'm activating Strings Translation

Hi there,

recently after updating WPML plugin and wordpress to the most recent version I started getting a following error when trying to login into admin panel:
There has been a critical error on this website. Please check your site admin email inbox for instructions.

If I turn off Strings Translation then backend loads.
I've already tried to rolling back to version wpml-string-translation.3.2.6. as advised in other blog with no luck.

I 've checked log file and it's throwing following error:
