plugins – Cannot edit Sidebar in any theme in wordpress


I am new to wordpress and so to the overall developers’ world 🙂

I am using the latest WordPress version and all the themes are updated.

The issue I am having is, I am not able to edit the Sidebar widget, for instance, I tried in Mismo theme, then in Storefront and so on. The sidebar widget just won’t be customised no matter which theme I use.

Getting below error, screenshot is also attached

TypeError: Cannot read properties of null (reading ‘length’)

at p (

at f (

at i (

at Fn (

at fe (


at (<anonymous>)


at [as useState] (

at e.useState ('''

Things I have tried-

  1. Tried switching to different themes
  2. Updating wordpress to latest version
  3. Uninstalling plugins like Yoast SEO, WooCommerce, Jetpack, Classic Editor etc.

Any help is greatly apprciated
