I see the option to share category. But there is no option to share posts. Previously, I used to have add this add on for my SMF forum. Wondering if I can have an easily visible share button under the post.
You know that if you edit a file of NodeBB itself it may refuse to update by git pull because a merge would be needed?
So it may be that you're working with an old version of NodeBB o_O
If you are able to delete a post you have the permission to also restore it. Because of this the post doesn't get removed but only gets less opacity (within the official themes).
I just don't know in which case the post could be removed from DOM after reload, may be an inofficial theme or an old version of NodeBB (maybe because of the reason above).
We've had people test Chrome, FF and IE... none work at the sites with these two firewall products, sadly. HTTPS might work. That's a pain until free certs are widely available 😞 Not practical to have tons of them.
