After I renamed some files, they disappeared from the Special Videos Page, although they are still present in the articles where they were uploaded. This happens to me on every wiki, but the one with the empty Special Videos page is this one because, after having noticed the problem, I have not renamed files (videos or images) on any other wikis where I'm active.
Could someone please tell me what caused this issue, or how to fix it? Thank you, whoever will answer this.
