Is anyone experiencing this error(image below) whenever they use the search bar to look for someone in bpip.org? The website works fine if you manually look for someone, but if you use the search bar, an error happens.

As soon as I received the notification from this post I immediately went straight to the bpip.org to check for myself and then I expirenced the same thing. I tried searching through my username but no positive results just the same thing as yours. I also tried using my profile UID and still the same. Other features works fine except the search bar.
You could just use the url to make the edit and search eg (
https://bpip.org/Profile?p=add the username of the user ) and send.
https://bpip.org/Profile?p=Chibit01
I tried with the URL and it worked. So I think op shou just use this method since it works.
