If have the same problem on my server.
I upgraded to 2.6.15 and i can edit, remove faqs but when i create a new faq it won't set active.
In the config is "activate new records" on (as it always was)
I see one problem: i am working in Dutch and the text at the active (actief) button shows only No (nee)
Al my older records are showing the same but are active.
An upgrade to 2.6.17 didn't help.
I am running this Faq for Years now without problems, but now i can't create new records.
I have another Faq still running 2.0.7 without problems.
Record administration is showing Yes and NO for activation and also for revision Yes and No
