        </div>
    </div>
</div>

all of ur javascript didnt work or just this? have u enable javacript to run in ur browser?

Have you include the jquery library before your scriptings? View the console tab in developer tools(F12) to see if any include is having error/warnings.

All javascripts. How do i enable javascript? i am getting this on the console log

TypeError: a.browser is undefined jquery.colorbox-min.js:4:2587

The error means that the link to the jquery.colorbox-min.js is wrong. Try to have the correct relative path for it.

Its a browser thing. I run a simiral project i have and colorobox and other javascripts play. I read that it might be a jquery conflict but thats not it too.

i erased everything and just used a colorbox example

<?php include_once 'includes/db.php'; ?>

        <script>
            $(document).ready(function(){
                $(".inline").colorbox({inline:true, width:"50%"});

                //Example of preserving a JavaScript event for inline calls.
                $("#click").click(function(){ 
                    $('#click').css({"background-color":"#f00", "color":"#fff", "cursor":"inherit"}).text("Open this window again and this message will still be here.");
                    return false;
                });
            });
        </script>
    </head>
    <body>
    <?php echo $base_url.'js/colorbox/jquery.colorbox.js';?>
        <p><a class='inline' href="#inline_content">Inline HTML</a></p>
        <!-- This contains the hidden content for inline calls -->
        <div style='display:none'>
            <div id='inline_content' style='padding:10px; background:#fff;'>
            <p><strong>This content comes from a hidden element on this page.</strong></p>
            <p>The inline option preserves bound JavaScript events and changes, and it puts the content back where it came from when it is closed.</p>
            <p><a id="click" href="#" style='padding:5px; background:#ccc;'>Click me, it will be preserved!</a></p>

            <p><strong>If you try to open a new Colorbox while it is already open, it will update itself with the new content.</strong></p>
            <p>Updating Content Example:<br />

            </div>
        </div>
    </body>
</html>

and getting this as error
