i have some problem with my style.
 

Ok lets start.
A few weeks ago i desainged a skin
Now i noticed that i have some problem like this

The first image is the problem
and the second image is what i want to do.

You want a border around the columns? Perhaps change the class of the table? tborder will give you a border.

where i can change it?
this is my problem.
i restore allmost everything to the defulet and its not working

You'd have to change the class in the template table. To find the template - vboptions > General Settings > Add Template Name in HTML Comments > set to Yes . Then go back to your page and view the source code and you will see the name of the template called around your part of the code. Sometimes the template is the one mentioned at the very top of the page source.

<!-- END TEMPLATE: threadbit --><!-- BEGIN TEMPLATE: threadbit -->

I don't think the threadbit template is the part that has the <table> tags. That would be above there and I think that is probably where you will need to change the class to tborder.

So thats what happend
i change to tborder but there is a Profit.
do you want a pic of this?

An image would help since I don't know what you mean. But, tbh, even a picture won't help too much. You really need to see the actual page itself. You should get the firebug plugin for firefox and it will allow you to change the class right there and see what happens.
