Upgrading to latest plugin version (4.3.3) causes setting page to be blank

After upgrading Google Analytics for WordPress to ver 4.3.3 the setting screen become blank. Only title shows.

This happens on some of my sites, on others there is no problem.

Reverting to version 4.2.8 solves the problem
