Question Problem with PDF attachments

Thanks for the template info. Don't have time to do that now; will check it out tomorrow.

This is the same problem with the Aurelia template.

don't know if update can fix it but you never know
I think I can only see this if I'm logged in to your forum but I can't I can't register.
"There is a post on our test website which contains all four attachment types:"

The post on our test site can be viewed by guests. The topic is "File Attachments".

I'm sorry but I can't see or find that topic when I use forum search button I get a warning on the screen.
so I guess it's not open to the public

Sorry, busy with a meeting, and now late at night.  The message you got seems to be from some custom code we run which looks for suspicious terms in URLs - but it shouldn't get triggered when you try to find that forum post.  It doesn't when I try using any browser - although it did two days ago when "attachment" and ".pdf" were both banned words in URLs.

I've attached an image of the post in my Chrome browser, as a guest user .  You should be able to see the direct URL in the address bar, so that should help.

Heading for bed - back tomorrow.
