@zenkamal @a_5mith This sounds like it's due the new way we store post bookmarks.
Before, we stored the pid (e.g. 2341)
Now, we store the post index (e.g. 5)
The bookmark only updates if the current post # is > than the bookmarked post #
Unfortunately, 5 will never be greater than 2341, so the bookmark never goes away.
The old bookmark is basically trying to load the 2341th post in the topic, which doesn't exist. You can clear the bookmark by clicking the "x" at the top right of the notification alert, then that topic should be fixed.
I just upgraded to the current git version of nodebb after I noticed that upgrading to 0.4.3. removed the Reply and New Topic buttons (no idea why that happened). The upgrade fixed that, but now when I try to create a new topic I just get the message "Category doesn't exist" when I click Submit (reply works though).
I'm running nodebb on Windows using mongodb. I had problems with categories before but managed to fix it manually, see https://community.nodebb.org/topic/1434/category-disappeared
