Playing around with upgrading to phpMyFaq 2.9.9 and getting this at the new setup page:
The following extensions are missing! Please enable the PHP extension(s) in php.ini.
ext/fileinfo
But when I run php -i I see: "--enable-fileinfo=shared" in the configure options. Plus 2.8 has worked fine forever (well, at least until recently when I encountered another problem I posted about).
