The top levels of all the forums look okay, except for the root/top level (
index.php) looks too big only when I'm logged in.
All the individual posts appear to be too big, independent of whether logged in or not.
When it's showing stuff too big, there's 4 lines of phpBB Debug info at the top of the page.
You've probably already noticed all this, but maybe there's a clue there.
[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 286: 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 the timezone 'UTC' for now, but please set date.timezone to select your timezone.
