Add url in a new item

i have a problem when i add in a new item with media… for example i add and url and I have this error
Error validating “/”. Cannot store files with the media type “text/html”.
Error validating “/”. Cannot store files with the resolved extension “html”.

Was the file that you wanted to add HTML? Those errors are saying that you don’t have HTML enabled for upload in the security settings.

You can change the settings to allow HTML files, but most of the time people don’t want or need to do that. Often when you try to upload a file by URL and you get HTML back, it means that you’ve used the wrong URL.

Or, if you just wanted to link to the URL, you don’t want to use Media for that at all, and would instead add a URL field in the main metadata panel.

thanks very much for the information
