How to search for user posts

Greetings. I was wondering if someone could explain why I am unable to search through user posts, including my own?

Specifically, whenever I attempt to click on "Find all posts by...", I am met with a message stating, "you do not have permission to access this page."

The search function has been completely broken on this forum for ages now—and honestly, who knows when they'll actually bother fixing it...☕

Yeah, the search bar has been pulled, and honestly, nobody knows if or when they might bring it back. I’m really sorry about that. :/

Topic.
