I upgraded to NodeBB 8.1 and re-install all npm modules. All seems OK.
But now the Guest can not see "image" and click the "broken link" , then "not-allowed" message is shown.
Possibly related to this admin option:
Posts/topics date format ("2 year ago" -> "20 may 2014")
Unregistred user can't see picture in topics
Registered users can now only see cats available to unregistered users.
Solved Finished the installation but can't see NodeBB in a web browser
"Track IP Address for each post" and Lavender Theme: Where Should I See The Recorded IP Address?
After upgrade to 0.8.0 I do not see my profile image
Do NOT Show "Log in to post" Button If User Can't Post to that Category
How can I let Guests Answer to Posts
