Hello @artf ,
I just did an upgrade of grapesjs from 0.14.61 to 0.17.26 and i have the following problems:
1.grapes.min.js:2 Plugin grapesjs-tabs not found
2.When i try to upload an image it says => grapes.min.js:2 {"error":"Internal Error","message":"Something went wrong! Please try again in a few seconds or contact support if the error persists."}
3.this.editor.Canvas.getWrapperEl is not a function when i try to previw page.

Thank u,
Nelida.
