Somewhere in the process of modifying woocommerce and adding a few plugins, builder no longer works on the home page, and only the home page. All other pages work. I tried disabling the last few plugins but nothing seems to work. I would probably need to give you editor access so you could see for yourself what’s going on. the site is: https://www.quickpictours.com.
I figured it out. It was a plugin called WP Fastest Cache. Once disabled I could edit, then turn the caching plugin back on.
Hey David,
Glad you figured out it out and thanks for sharing! For caching plugins, we recommend WP Rocket as it works best with BB. Anyway, enjoy The Beaver!
