I’ve got the fix. All you have to do is place 3 “..” (no quotes) and everything will be fixed !
Go to showfiles.php and on line 25 and change this
$image = str_replace('../', '/wp-content/plugins/wp-admin-icons/', $image);
to this
$image = str_replace('../', '../wp-content/plugins/wp-admin-icons/', $image);
THEN
Go to icons-scripts.js and make sure line 75 looks like this
jQuery(".myIconList").load('../wp-content/plugins/wp-admin-icons/includes/showfiles-upload.php', function(response,
and line 177 should be this
var url = '../wp-content/plugins/wp-admin-icons/includes/showfiles.php';'
PS: If you want your uploads to show you have to change line 29 of showfiles-upload.php
$icon_str = "<li><img src='".$sitename."../wp-content/plugins/wp-admin-icons/icons/uploads/".$iconsArray."'
Thats it ! (so far so good)
