Thanks for your answer. I have also consulted Sucuri and they tell me the same thing as you about renaming media files. Still I have a problem with scaling and the screen where I edit media-files do not show correctly, but that is not your problem I suppose. I have updated all my plugins to latest version and I think I have to inactivate them one by one to see if some plugin interfear with this function.
And again thanks for quick and accurate answer
