Error_log implode() php

Hi,

First thank you for this amazing plugin with many features. I purchase pro version.

I’m using enfold theme. When i update my amp plugin from 0.9.97.51.1 to recent version i have an error_log in my server:

implode(): Invalid arguments passed in /home/public_html/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/shortcode-helper.class.php on line 163

When i downgrade my plugin to 0.9.97.51.1 the error gone.

I submit this ticket in your site in Support section about 3 weeks ago but no one give me any answer

Please help me for this issues.
