Everything working ok without the grapesjs-project-manager plugin.
It is a fresh install of GrapesJs with these plugins:

    <title>GrapesJS</title>
    <link rel="stylesheet" href="dist/css/grapes.min.css">
    <link rel="stylesheet" href="plugins/templates-manager/dist/css/grapesjs-project-manager.min.css">

    <style>

        fromElement: true,
        pageManager: true, // This should be set to true
        storageManager: {
          id: 'gjs-',             // Prefix identifier that will be used inside storing and loading
          type: 'indexdb',          // Type of the storage
          autosave: true,         // Store data automatically
          autoload: true,         // Autoload stored data on init
          stepsBeforeSave: 1,     // If autosave enabled, indicates how many changes are necessary before store method is triggered
          storeComponents: true,  // Enable/Disable storing of components in JSON format
          storeStyles: true,      // Enable/Disable storing of rules in JSON format
          storeHtml: true,        // Enable/Disable storing of components as HTML string
          storeCss: true,         // Enable/Disable storing of rules as CSS string
        },

Pls, help!
