ok, you messed up the new widget area code which caused an issue in the parser. If you look at the directions, each arameter needs to be seperated by a '&' nad you seperated them by a space: ie. you had
HTML Code:
<?php bfa_widget_area('name=Footer widget area cells=3 align_1=9 align_2=2 align_3=3 before_widget=<div id="%1$s" class="header-widget %2$s">&after_widget=</div>'); ?>
when it should have been
HTML Code:
<?php bfa_widget_area('name=Footer widget area&cells=3&align_1=9&align_2=2&align_3=3&before_widget=<div id="%1$s" class="header-widget %2$s">&after_widget=</div>'); ?>
in addition, you are creating a footer widget, but you didn't change the class which is ;header-widget' which could get confusing.
Since you are starting out, why not just create a single widget area with
HTML Code:
<?php bfa_widget_area('name=Footer widget area'); ?>
At any rate it took me quite a bit of time, but I was able to fix the export and remove the offending code. Here is a fixed version with just the one footer widget area.
