I've got my website for one year now and I publish about 3-6 posts per day.
Today, when I tried to write articles I couldn't do it properly.
When I want to insert a media, the normal lightbox doesn't show up. As I was clicking on any button at all.
When I want to add a link to a word, it shut my post.
When I want to define the image cover of the post, the lightbox loads but with the old version of wordpress looks.
When I'm in text interface, there is no buttons such as "bold", "italic", "link",... The bar is empty.
I already re-installed last version of wordpress. Nothing has changed.
