It was supposed to be a bug with this 403 response codes for topics. Not sure why it wasn't fixed.
https://invisioncommunity.com/forums/topic/466289-error-pages-404-vs-403-no-permission
@Jim M It's about forums and topics that you do not have permission to view. Let me give an example:
https://invisioncommunity.com/forums/forum/15-test-posting/ returns 404 for guests (forum is hidden from guests) - OK
https://invisioncommunity.com/forums/topic/472383-test-topic/ returns 403 for guests [should return 404]
@Daniel F stated that topic should also return 404 to hide the fact that topic exists at all.
But I mean you can only make a reply using the full editor that is located below the last reply, correct? There is no other option to open the editor in another page (like when creating a new topic)?
Could you please leave an option to serve CSS directly from the website, not only via CDN? It's not that CDN will always make site faster. Would be nice to have a choice.
