Hi,
A similar problem occurred to me. When I try to edit the Main Page at 85% I get the message “Fatal error within the Pagelayer iFrame as pagelayer object not found! Please contact Pagelayer support ”I tried to deactivate one by one of my installed plugins. At one point the problem disappeared when I deactivated the plugin ‘ELEX WooCommerce Product Price Custom Text (Before & After Text) and Discount’. To be sure, I tried to turn this plugin on and off several times and it is definitely the cause of that error for me.
