Hi, HollyW00d.
The instructions on that website are fairly generic and you will need to use your own knowledge and experience to implement them. The advice is quite old – filenames may not be exact, line numbers may have changed. You’ll have to think about what you are doing.
The purpose of the “comment out line 51″ instructions is to prevent the theme from calling some JavaScript that will cause an error if you remove the actual theme menus – which is what you are going to do in order to replace them with UberMenu. Below is the relevant code from the footer-default.php file:
<?php // Main menu dropdowns ?>
<script type="text/javascript"><?php
if ($theHeader['menu_left']) {
echo 'if ( jQuery("#MM ul").length ) { ddsmoothmenu.init({ mainmenuid: "MM", orientation: "h", classname: "slideMenu", contentsource: "markup" }); }';
}
if ($theHeader['menu_right']) {
echo 'if ( jQuery("#MM-Right ul").length ) { ddsmoothmenu.init({ mainmenuid: "MM-Right", orientation: "h", classname: "slideMenu", contentsource: "markup" }); }';
}
?></script>
You’ll need to either delete all of this code, or just comment out the the echo
statements. I have read that with the Mingle theme commenting out only the echo
statement for the left-hand menu is enough. I really don’t know, I have never tried it myself. Unfortunately the support team is not able to hold your hand through these types of plugin installations that require you to modify the core theme code. We will always point you in the right direction, but you will need to figure it out and implement whatever is necessary for yourself.
