Hi - I am trying to create blog posts using elementor. I have watched video tutorials where you use the 'Drag widget' function to create say an empty 'box' or column where you can then add in images or text etc. However, when I try, I can create the empty box, but when I try and drag over , for example, the Text Heading, I get a circle with a line through it ( as in forbidden or not allowed) and I'm unable to drag and drop it in. I can't drag and drop anything in. This is making it impossible to create my own posts - I can use a Theme but not create my own structure. What am I doing wrong?
