[SOLVED] Errors after installing Butterfly script. I Need some help...

Hello,

I know that this is an old script, but I want to use it.

I already posted on their forum, but this forum is almost dead

I'm not a programmer, but I know to play a bit with copy/paste on to the codes

I managed to install bfm on hostagator account after importing the db from an older PHP script instalation

Ok, now after install I have this errors on to the top of admin area:

"Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CST/-6.0/no DST' instead in" folowing locations:
