Hi Olga,
i removed the woocommerce files in xstore child theme.
i think i narrowed the problem down to the functions.php.
1) I switched to Storefront theme and then only activated the WPBakery plugin. It worked.
2) When i activated Woocommerce plugin, the frontend editor of WPBakery stopped working.
3) When i removed my own code from functions.php (with Woocommerce plugin activated) the frontend editor keeps working
4) when i place back my own code in functions.php it stops working.
How can i debug what code is causing the error? Could you please check the functions.php
All worked before the latest update.
Hop you can assist me.
