Edit the artisteer-overrides.css file

change from this:

div.mojo-tabs ul  > li::before, 
div.adminmenu ul.simplelist  > li::before ,
ul.simplelist   > li::before,
div.gallerymodule ul  > li::before,
ul.simplehorizontalmenu  > li::before,
ul.tag-cloud  > li::before,
ul.blognav  > li::before
{ content: ''; display:block;}

to this:

div.mojo-tabs ul  > li::before, 
div.adminmenu ul.simplelist  > li::before ,
ul.simplelist   > li::before,
div.gallerymodule ul  > li::before,
ul.simplehorizontalmenu  > li::before,
ul.blognav  > li::before
{ content: ''; display:block;}

ul.tag-cloud  > li::before { content: ''; }
ul.tag-cloud  a { padding-right:5px; }

Hope that helps,

Joe

you could try adding it if it isn't there already.
