I like the fact it's light weight.. the only thing I would suggest out of the box is bbcode tags, at least for posting images. Maybe that's already in v2?
try editing you /etc/my.cnf file and see if you're in "TRADITIONAL" sql mode
search for sql_mode
If you are, then comment that out, restart mysql, install, and then re-enable that flag in my.cnf
solved it for me
