I better ask since I am not quite sure:
Existing codeblock:
# do not show rightbar box if RightBar is empty
global $HTMLStylesFmt;
$prb = FmtPageName('$FullName-RightBar',$pagename);
$grb = FmtPageName('$Group.RightBar',$pagename);
$srb = FmtPageName('$SiteGroup.RightBar',$pagename);
if (PageExists($prb)) $rpage = ReadPage($prb);
if (PageExists($grb)) $rpage .= ReadPage($grb);
if (PageExists($srb)) $rpage .= ReadPage($srb);
if($rpage['text']=='') {$HTMLStylesFmt[] = " #rightbar { display:none } \n";};
Is it sufficient to write the last line as this:
if(@$rpage['text']=='') {$HTMLStylesFmt[] = .......
?
Best,
