I just installed a Fusion subtheme in a new Drupal7 site.

On ALL my site's /admin pages, but NOT on Visitor's (not-logged-in) pages, I see these dialog boxes:

Notice: Undefined variable: main_group_width in include() (line 38 of /srv/dev/sites/dev.dt.loc/themes/dt_d7_fusion/templates/pages/page.tpl.php).

Looking at my version of that file it's just:

34  <div id="main-wrapper" class="main-wrapper full-width clearfix" >
35   <div id="main" class="main region <?php print $grid_width; ?>" >
36    <div id="main-inner" class="main-inner inner clearfix" >
37     <?php print render($page['sidebar_first']); ?>
38      <div id="main-group" class="main-group region nested <?php print $main_group_width; ?>" >
39       <div id="main-group-inner" class="main-group-inner inner">
40        <?php print render($page['preface_bottom']); ?>
41         <div id="main-content" class="main-content region nested">
42          <div id="main-content-inner" class="main-content-inner inner">

Google turns up the error in two other Fusion-related posts:

http://drupal.org/node/931544
http://drupal.org/node/1121678

But I don't understand yet what to do about it.

Is this happening with the Fusion core theme also? Which subtheme are you using?

Core is in involved, of course, as the parent theme.

I see this issue in each of the main themes that use $main_group_width,

cd sites/all/themes
grep main_group_width `find . | grep page.tpl`
 ./fusion/fusion_core/page.tpl.php:            <div id="main-group" class="main-group region nested <?php print $main_group_width; ?>">
 ./acquia_marina/page.tpl.php:            <div id="main-group" class="main-group region nested <?php print $main_group_width; ?>">
 ./acquia_prosper/page.tpl.php:            <div id="main-group" class="main-group region nested <?php print $main_group_width; ?>">

and any subthemes based on them.

This issue's reported on my own custom subtheme.

Hi dtwork, could you post your subtheme's .info file?

hi dtwork,

I think this is missing. You can insert it anywhere.

; Nested group width adjustments: adjacent regions to subtract for correct group width
settings[grid_adjusted_groups][main_group][] = sidebar_first

Just a note to say I had this error start occurring when creating a sub-theme off Fusion.

I used the same fix and it worked (™)
