"Missing post number" refers to a situation where a post or comment on the Physics Forums website does not have a visible number associated with it. This can make it difficult to reference or link to the post in discussions or debates.
There are a few reasons why a post number may go missing on Physics Forums. It could be due to a technical glitch or error, a deleted post, or a post being moved to a different thread or forum.
In most cases, a missing post number cannot be restored on Physics Forums. However, if the post was simply moved to a different thread or forum, the post number will reappear once the post is located.
A missing post number can make it challenging to follow or reference specific posts in discussions on Physics Forums. This can lead to confusion and may disrupt the flow of the conversation.
Unfortunately, there is no way to prevent post numbers from going missing on Physics Forums. However, you can try to save a copy of the post or comment for your own reference in case it does go missing in the future.
