THE SYSTEM : Windows 7 / WAMP / flourish_r1040
THE BUG : a space on top of my php pages, and MSIE in quirk mode
THE ISSUE : There were BOM characters between all include() or $tmpl->place() (seen on moz-firebug)
THE SOLUTION : Convert all PHP files in "UTF8 without BOM" (my files AND Flourish files)
Nota : most of Flourish files were in... ANSI mode (maybe during dezip ???) and all my files were in UTF8.
I hope it will help... :)
