col-lg-3 / col-lg-9 kicking in erroneously

@SirClickalot
There may be different possible situations.
The most common is that region is considering block availability which means block is have some invisible white space or values.

Thanks Ravi → ,

I had figured that was the problem and there was indeed some 'white space' being thrown out by a view.

This seems to happen all the time with Views and simply setting Hide block if the view output is empty: Yes just does not work.

HOWEVER, for anyone else suffering from this frustration with Views, the Views Minimum → module completely solves the issue.

Outstanding work Kevin Quillen (kevinquillen) → !

I use it alongside the Block Visibility Groups → module to great effect.

It looks like empty rows can be output, even if "Hide if empty" is enabled for a views field: 🐛 "Hide if empty" ignored for fields Active . Maybe this could also lead to empty blocks getting rendered?

@SirClickalot

If you are creating template in your theme for this views then you may try render|trim as below

  <div{{ row.attributes.addClass(row_classes) }}>
    {{- row.content|render|trim -}}
  </div>

@SirClickalot
Are you still getting same error?
