[HELP] SuSocial Error 43 – Profile not switching anymore with Facebook’s new UI (2025)

Hey everyone,

I’ve been using SuSocial daily for over a year with zero issues, mainly for posting and bumping in multiple Facebook groups through my personal profile.

But recently, I keep getting this persistent Error 43 – “Failed to switch to profile – profile not identified” whenever I try to post, even in manual or semi-manual mode.


:white_check_mark: Here’s what I’ve already tried:

  • Language set to English (US)
  • Maximized embedded browser window
  • Logout/Login
  • Changed password
  • Cleared cache/cookies
  • Disabled simplified posting method
  • Enabled manual browsing
  • Tried Chrome, Edge, Firefox, and even the Facebook Windows app

Despite all this, Facebook doesn’t stay on my main profile (“Guillaume Blanc”). Every time I try to publish, SuSocial fails to detect the correct profile and crashes the post.


:mag: What I believe is the root cause:

Facebook’s new multi-profile system and “See all profiles” interface broke the way SuSocial handles profile switching.

Even if I manually switch to my real profile inside the Embedded Browser, it resets after a few seconds or shows a blank selector, and I get Error 43 again.


:x: Consequences:

  • No auto-posting works
  • No bumping works
  • SuSocial can’t lock onto the correct profile anymore

:question:My question:

  • Has anyone found a workaround or fix that actually sticks in 2025?
  • Are there any reliable alternatives to SuSocial that work with Facebook groups and the new profile switching UI?
  • What’s your experience with tools like JarveePro, Socinator, or custom browser scripts?

Thanks in advance — this is killing my group strategy and I know I’m not the only one affected since Facebook is rolling this new system to everyone.

Guillaume
