Do you have the latest theme version? Please make sure to have theme updated and all included plugins as well.
Try re-installing theme again. Let us know how it goes.
I have update all plugin. I found that it is failed to save when using WPBabery Page Builder frontend editor. All text field cannot be save but I can update the layout change.
But however, if I change to backend editor, it is ok to modify everything. What’s the problem?
1-To edit page using the WP Bakery, first open page from Pages menu or click on the “Edit page” option at the wordpress top bar (screenshot), then click on “Backend” button. Screenshot.
2-You have to install & activate the “Tablepress” plugin first. It is free. Then create at least one table in it. So that you can select this table in the element in your page.
