To change the older/newer to arrows you need to edit the theme.
1. Go to Appearance > Editor
2. Select Main Index Template
3. Find the code:
<?php next_post_link('%link', 'next', TRUE, ''); ?>
<?php previous_post_link('%link', 'previous', TRUE, ''); ?>
and change it to:
<?php previous_posts_link('←') ?> <?php next_post('%', '←', 'no'); ?> <?php previous_post('%', '→', 'no'); ?> <?php next_posts_link('→') ?>
<!--<?php next_post_link('%link', 'next', TRUE, ''); ?>
<?php previous_post_link('%link', 'previous', TRUE, ''); ?>-->
(you're keeping the old code in case you need to switch back or something gets screwed up)
Remember, when you update WPFolio you'll have to change this (unless we change it in the theme, which we might).
The "edit this entry" text only appears when you are logged in. It's for convenience. Visitors to your site don't see it.
