The $(…).modal is not a function is usually caused because scripts are loaded in the wrong order . The browser will execute the scripts in the order it finds them. If in a script you attempt to access an element that hasn't been reached yet then you will get an error. Make sure that you don't have a script above one that it requires.

Plugin dependencies

Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files).

Multiple jQuery instances

Sometimes this warning may also be shown if jQuery is declared more than once in your code. The second jQuery declaration prevents bootstrap.js from working correctly. The problem is due to having jQuery instances more than one time. Take care if you are using many files with multiples instance of jQuery. Just leave one instance of jQuery and your code will work.

Hello, You're correct that jQuery scripts should be added before dataTables. I think that the other errors are also connected with the order of scripts added to Your page. It should be like this:
  1. jQuery
  2. popper
  3. bootstrap
  4. mdb
  5. dataTables

I just solved the demo code I needed to load jquery-3.2.1.min.js before the jquery.dataTables.min.js script as follows :-

<script type="text/javascript" src="js/jquery-3.2.1.min.js"></script>

<script src=""></script>

I still have some errors on my project code, but I will build it from this template hopefully ..

Uncaught TypeError: $(...).sideNav is not a function
at transactions-a.php:31
(anonymous) @ transactions-a.php:31
22:30:49.875 transactions-a.php:688 Uncaught TypeError: $(...).modal is not a function

Thanks Colin
