DLE 9.6, news is not added to the site, what's the problem?

Question

DLE

I use DLE 9.6 on my site. Everything worked fine, until today, I try to add news or edit an existing one, but I get this error "Title is required when writing an article." What could be the problem? I didn't change the addnews.php file

Answer 1

And the template? and such an error when adding through the site or through the admin panel too??
