nothing happens! any help appreciated

It could be a PHP error. First, try resetting the page to its defaults, then change your filename input to something simple that’s all plain text and experiment with selecting different pages/posts to make sure it’s not a specific post that is causing the problem. If that still doesn’t work, can you right click on the page and select “inspect element”, then, depending on your browser (I’m using google chrome), select the network tab and then try to create again. A new entry in the network tab should show up. Click on it and select the ‘response’ tab. If it’s a php error you will see a whole bunch of html. Can you paste that here so I can see the error?
