ISSUE: Boutiques content fields are not loading in the page editor.
If you’re using the new block editor that was released with WordPress 5.0, the Classic Editor plugin is required to run Boutiques (here’s why). If you don’t already have it, you’ll see a notice to install and activate it during the installation process for Boutiques.
Once you have installed and activated the Classic Editor plugin, go to Settings > Writing and make sure the Allow users to switch editors setting is set to “Yes.” Then, when you open your Boutiques page for editing, you’ll see an option to Switch to the Classic Editor. It looks like this:
From here, you can change the Page Attributes template and load your desired Boutiques template fields.
