Have you tried it with a new database and a new extension added there?
Specifically, I use the following for AO3 in the personal.ini:
Code:
[archiveofourown.org]
username:Maysupersecretusername
password:365Dayswithfreebeer
is_adult:true
extragenres:
extracategories:
extratags:
custom_columns_settings:
category=>#ts
fandoms=>#ts
There might be some nonsense in there, but it works for me.
Ok, I don't think I need to mention that these are not my real login details, do I?
