Good morning everyone 

I use the original theme

all my files

ow_pluginfiles

ow_userfiles,

ow_static,

ow_smarty/template_c ..are777

my config.php 

define('OW_USE_CLOUDFILES', false);

if ( defined('OW_CRON') )

{ 

define('OW_DEBUG_MODE', false);

define('OW_DEV_MODE', false);

define('OW_PROFILER_ENABLE', false);

} 

else 

{ 

/**

* Make changes in this block if you want to enable DEV mode and DEBUG mode

*/

define('OW_DEBUG_MODE', false);

define('OW_DEV_MODE', false);

define('OW_PROFILER_ENABLE', false); 

}

when I write something on edit css

.ow_site_panel {background:url("http:/sitename.com/ow_userfiles/themes/theme_image_29.png");}

or

.ow_console_body {

 background: #5882FA;} 

there is no change..everything remains the same
