Format errors after upgrade to 5.6.0.2
Permalink<?php $is_edit_mode = Page::getCurrentPage()->isEditMode() ?> <?php if(!$is_edit_mode): ?> put your import code here <?php endif; ?>
Basically what the above does, is checking if the page is in edit mode, and if it isn't then loads the files you define.
Why you need to add the code above is to have your code only imported when NOT in edit mode. That might be required if you are to use bootstrap or jQuery.ui in your theme, since c5 also imports the same (but slightly modified versions) when in edit mode. Import of the libraries more than once might give you unexpected behaviour.
It might also be you have the same css class names or ids as c5 uses in edit mode (but highly unlikely) which messes with your site.
EDIT: Oh, the code should wrap your imports in <head>
Please see my pm (if you haven't already).
Line 30: [class*="span"]!{float:left;margin-left:20px;}
Now all my formatting in dashboard edit mode is correct.
It might be a double import of jquery.ui.js or a bootstrap import in your theme that interfere when in edit mode.
