I installed Google Analytics Dashboard for WP (plugin version 4.9.5, WordPress version 4.7.1–he_IL). After the activation our site’s bounce rate in Google Analytics fell to zero. I tried to deactivate plugin, and the bounce rate jumped back to 68%:
Is it bug or some wrong setting?

Thank you for the quick answer. I’ll check the code again for manually added tracking codes.
