how many posts do you have in ur blog ?
it depends on ur reading settings on ur blog admin area.
please go to ur blog admin area >> Blog pages show at most >> set it to 3 or 2 and update ur new setting , and go back to ur blog and reload the page , you should see 3 or 2 posts in the ur blog main page , cause most wordpress themes the previous and the next entries codes are included .
BUT , if you still can not see the next and previous entries link then you should do this :
1- first backup ur index.php file "copy it to somewhere"
2- open index.php with text editor "i prefer Notepad++" and search for :
<?php next_posts_link('« Older Entries') ?>
<?php previous_posts_link('Newer Entries »') ?>
if not found then the code is missing and you need to add it .
NOTE : Please if you dont not know how to do it , then send me the index.php of your theme and i will do that for you
i wish this gonna help you
