I created a how-to article and published it, so I could download it to PDF.
Now I can preview the file or export it to PDF/Word and it has all the content that I created. However, when I click on 'edit', it shows me a blank document, which means I cannot correct anything in the article.
I tried copying the article to see if it's going to allow me to edit the content I can preview, but it's all the same - preview is fine, but no content to edit.
