Ok well something has happened to it. If you search for DHT11 PIC code there are only 2 (maybe 3) postings the rest have disappeared.
This is the link from the Forum it only has 2 posts
https://www.electro-tech-online.com/threads/dht11-and-oshonsoft-pic-code.132327/
These were the original starting posts. Somehow they have become fragmented into separate threads.
I'm not suggesting the Moderators "did" something but they are the only ones who can fix anything.
