Left behind CSS class ‘.full-width’ can break the output of certain themes

Symptoms

The issue can be reproduced easily using BeTheme “Page Options” editor. In any page of the theme, when you try to insert a new column, edit it (using the pencil icon) to insert some text content to it, when the editor opens it is squeezed in the left side.

Workaround

The problem can be safely solved by removing the culprit CSS class in this file: resources/css/dd-general.css, line 461:

.full-width{display:block;float:left;clear:both;position:relative;}
