Which technology do you use with our MDB package? Did you check the solutions above? If they didn't help - could you create a snippet with your problem without the involvement of another framework?

Best regards

I have the same Error. TypeError: t is undefined, when i click of one of the gallery-photos.Here is my code:

<!doctype html>

    <title>Hello World</title>

    <link href="./../resources/mdbpro/css/bootstrap.min.css" rel="stylesheet">
    <link href="./../resources/mdbpro/css/mdb.min.css" rel="stylesheet">


<div class="container">

    <div class="row">
        <div class="col-md-12">

            <div id="mdb-lightbox-ui"></div>

            <div class="mdb-lightbox">

            <figure class="col-md-4">
                <a href="" data-size="1600x1067">
                <img alt="picture" src="" class="img-fluid">

            <figure class="col-md-4">
                <a href="" data-size="1600x1067">
                <img alt="picture" src="" class="img-fluid" />

            <figure class="col-md-4">
                <a href="" data-size="1600x1067">
                <img alt="picture" src="" class="img-fluid" />

    <script src="./../resources/mdbpro/js/jquery.min.js" ></script>
    <script src="./../resources/mdbpro/js/popper.min.js" ></script>
    <script src="./../resources/mdbpro/js/bootstrap.min.js" ></script>
    <script src="./../resources/mdbpro/js/mdb.js" ></script>
        $(function () {



I have simplified my example above. In my original code I linked $("#mdb-lightbox-ui").load("./../resources/mdbpro/mdb-addons/mdb-lightbox-ui.html"); via script call. The problem was that I entered the wrong path there. So it is correct, as shown in my example $("#mdb-lightbox-ui").load("./../resources/mdbpro/mdb-addons/mdb-lightbox-ui.html");.

Hi. I created the project using your code and I have no error in the console. Which MDB version are you using?

Tenarius free commented 4 years ago

Thanks for looking at this. I have the solution. In this example, I simplified my code for demonstration purposes and basically solved the problem. The problem was $("#mdb-lightbox-ui").load("./../resources/mdbpro/mdb-addons/mdb-lightbox-ui.html");. In my example, I adjusted the path correctly. I even edited that in my post afterwards. In my original code I had linked this part with <script src ="./../resources/js/scripts/scripts.js"></script> and there for mdb-lightbox-ui.htm wrong path specified. Unfortunately there was no more precise error message. Disgusting mistake. Thanks for the second opinion and the food for thought. <3

Hi herfelp, Can you create a snippet with your code example so I can examine what causes this error?
