Hey aev, indeed, long time no see.
Your error message indicates a conflict concerning the username/password combination.
This is what you should try:
- Log out from the forum
- Clear your browser cache
- Log in back to the forum.
In case you logged in successfully, your Username/Password-combination would be correct.
Log out from the forum again. Clear the cache and now enter exactly the same credentials into the TripleA PBF-mask. Try to post and it should work.
If your above re-login to the forum failed, you would have entered an incorrect (maybe old and outdated) password. In that case you should either remember the current one or ask for a new one.
Let me know what happens. Good luck!
