Hi,
readonly problem
the textboxes are not readonly, your CSS set font size to 0px, so to solve this issue replace in file /templates/design_control/css/template.css at line 132 this:
font-size: 1.0em;
with this
font-size: 12px;
icons problem:
you have some error with your CSS in file /templates/design_control/css/font-awesome/css/font-awesome.min.css. Contact your template provider. Now to work I have disabled "ENABLE FONT AWESOME?" from Extensions->Template Manager->design_control - Default->General
Another problem
there is a javascript conflict with Date field, your template load all jquery plugins (
many never used), this cause a conflict with our date field that use one of these plugins. To load many javascript never used is a
bad bad choice, your site will work more slowly and increases the load of the clients (+120Kb plugins, 200Kb UI framework).
Anyway to solve this conflict with our date field, please replace /templates/design_control/js/jquery/jquery-ui-addons.js file with attached, only differences we have removed last 2 lines.
