I'm using TikiWiki v1.9DR4 (CVS) -Sirius-, and I'm having an odd problem. Until recently I was able to make changes using the General Config page, but now it's not accepting my changes. I'm not getting an error message or anything; it's just silently ignoring any changes I've tried making on that page (ie, date formatting, session lifetime, etc). Other admin pages seem to work OK.
It's rather annoying. I'm still testing, so if need be, I can toast my installation and reinstall from scratch; but I'd like to know what's going on, in case this happens when there's actual live content in place.
