SmartCrawl conflicting with WooCommerce

Whenever I enable SmartCrawl, the home page becomes blank. There are no errors in the console. I enabled the debug log and found the following in it.

[29-Sep-2018 13:15:24 UTC] PHP Fatal error: Uncaught Error: Call to undefined method Smartcrawl_OnPage::_tags_to_keywords() in /home/++++/***
Stack trace:

#6 /home/+++/**** wp_head()
#7 /home/+++/**** require_on in /home/++++/*** on line 755

I did a Plugin Conflict test and found that it is a conflict with WooCommerce.

I am transferring the products from WooCommerce to MarketPress.
