Hi,
I’ve discovered a very minor HTML error where attachments are listed:

<div class="d4p-bbp-att-wrapper">
<a class="" download href="http://domain.org.uk/file.pdf" title="File.pdf">File.pdf</a>
</div>

Notice the word download should be inside the class quotes and not in between the quotes and the href tag.

Where is this?
This is generated by bbpress or a plugin like wp-wrapper..

I have the GD Attachments plugin installed, so when you add an attachment this markup is generated.

best way – to write wordpress.org/support/plugin/gd-bbpress-attachments/

Although the author of the plugin (Milan) regularly visits here.
