Forum OpenACS Q&A: OpenFTS mystery

I've successfully installed and used OpenFTS several times (Redhat 7.2 and Suse 8 with postgresql). But I've been failing in the last few days, trying both 4.6.2-beta2 and with 4.6 head. I'm using notes package for testing. I was finally going to post here and ask, why is this happening? --

I'd reinstalled a few times, followed the new instructions, referred to the old instructions, restarted extra times, etc. Finally thought hey! I'll set debug to true and see what I find. I swear I did nothing else (directly). And it started working:

I changed debug back, it still works now. Does that make sense? And what sort of thing might be wrong that could cause that first error? Thanks
