Is the Allowable File Extensions in DNN 9 missing or simply hidden?
The good news is that it’s still available.
The Allowable File Extensions is a list of those file types configured by their file extension which are permitted to be uploaded to the website.
It’s given as a comma separated list within the site’s admin configuration.
Previously it was to be found under the Host > Site Settings page.
Looking under the site configuration in DNN 9 I was unable to see the Allowable File Extensions configuration textbox.
It’s still there, but now moved under the Security option.
Begin by selecting the Security menu from the options on the left black panel
On the security menu select the more tab at the right hand end. Opening this section.
On this tab we have the options for SSL Settings and still More Security Settings. This is the one which we are interested in. Click on it.
Finally we have the page which we are interested in, More Security Settings.
Scroll down the page to the last textbox which shows a list of the different file types which are supported. Add or remove to suit your website requirements.
The Allowable File Extensions isn’t lost/missing. It has been moved under the Security menu section.
