When I use the Source code of "Developer Guide", like this:
mymodule_page.tpl
Welcome to my shop!
mymodule_page.php
<?php
global $smarty;
include('../../config/config.inc.php');
include('../../header.php');
$smarty->display(dirname(__FILE__).'/mymodule_page.tpl');
include('../../footer.php');
?>
in prestashop1.4,my "Welcome to my shop!" line neatly placed between header, footer and columns,It is correct.
but in prestashop1.5.0.5,my "Welcome to my shop!" shows incorrect,it just placed between header and footer,leftcolumns and rightcolumns is invisible!why the Source code is same,but leftcolumns and rightcolumns don't show?I use the default theme of prestashop1.5.0.5.
look at Attach Files
who can help me,Thank you very much!
