Solved Divi/Woocommerce fatal error

Hi all,

We have had a Divi site running for over a year with a Woocommerce plugin enabled and used it with the Divi Shop module.

As of 8/1 the entire site went down with a critical error.

We removed all plugins and added one at a time and found that when we activate Woocommerce it brings the entire site down.

We restored from 2 days before and the site still wouldn't come up until we disabled Woocommerce.

We also restored an earlier version of Woocommerce from a prior release (we were on 9.1.4 but reverted to 8.8.5) and still activating Woocommerce causes the error.

In the log file we see errors in the Divi theme directory.
PHP Fatal error: Uncaught Error: Call to undefined function et_core_cache_has() in /nas/content/live/nudvctmdl/wp-content/themes/Divi 2/includes/builder/feature/background-masks/Functions.php:48#012Stack trace:#012#0 /nas/content/live/nudvctmdl/wp-content/themes/Divi 2/includes/builder/feature/background-masks/PatternFields.php(266):

I'm not sure why restoring from a few days prior to the error isn't resolving the issue, but I wanted to post here if anyone had any thoughts.

Do we perhaps need to upgrade to a newer Divi theme? And how can we see on the WP dashboard what Divi version we currently have (we inherited this site)?

Thanks for any thoughts...

 

Needed to upgrade the Divi theme as the old version of the theme's folder was erroneously named "Divi 2". That fixed the issue.
