Do you mean the special hover effect that displays the whole link and link title that comes up when you hover the mouse over the link?
That is controlled by CSS which is found in your style.css style sheet. If it came with the Theme and you didn’t put it in there, then contact the Theme author and find out how to remove the hover effect (which is a gimmick that a lot of people want on their site).
As for the “View all posts”, you can change either the wp_list_cats() or list_cats() template tags to include the description of the category which is set under Manage > Categories instead of the default English. You can find more information on these tags and how to customize them at template tags – wp_list_cats.
Your site is using the “nice titles” javascript to display those mouseover titles.
In your site’s script directory
looks like:
themes/falling_dreams/nicetitle.js
open nicetitle.js and locate the text you want to translate.
be careful only to translate the perscribed output text, not the php or js tags.
or
If you don’t want the nice title effect, you can turn that off by editing your header.php and removing this line:
<script language="javascript" src="http://www.dungeon.com.br/wp-content/themes/falling_dreams/nicetitle.js"></script>
Then you’llbe at liberty to change your titles or hover effects to anything you’d like them to be.
