The error mesage was:
You’ve reached the maximum number of topics a new user can create on their first day. Please wait 2 hours before typing again.
This seems to be controlled by: ‘max topics in first day’ - adjusting this removed the error.
The issue is, that the user has 8 previous Topics with the first being 4 days ago. So I think they shouldn’t be affected by this setting, seeing it is meant to only affect the 24hr period after the user’s first post. The posting account is a TL0 user.
Option description is:
The maximum number of topics a user is allowed to create in the 24 hour period after creating their first post
I’d make a speculative guess that the setting might really be ‘maximum posts per day for TL0 users’.
It may be worth checking if this is also the case for the ‘max replies in first day’ setting.
