Bootstrap modal no longer showing since adding new script tags

I am using bootstrap modal but I noticed that since I changed and added further bootstrap downloaded files, it has stopped working. It may not be the script tags causing it, but I noticed that up until then, it was working.

I also added the bootstrap courousal but I have removed it now, and it still isnt showing (the modal)

No errors are showing in the console.

I have included my code below;

SCRIPT TAGS:

<script type="application/javascript" src="libs/js/leaflet.markercluster.js"></script>       
<script type="application/javascript" src="libs/js/bootstrap.bundle.min.js"></script>    
<script type="application/javascript" src="libs/js/jquery-2.2.3.min.js"></script> 
<script type="application/javascript" src="libs/js/script.js"></script> 

Answer

Reorder your <script> tags as follows.

<script type="application/javascript" src="libs/js/jquery-2.2.3.min.js"></script>
<script type="application/javascript" src="libs/js/bootstrap.bundle.min.js"></script>
<script type="application/javascript" src="libs/js/leaflet.markercluster.js"></script>
<script type="application/javascript" src="libs/js/script.js"></script>

jQuery should usually come first, or at least included before Bootstrap, followed by other plugins that usually depend on them with your own scripts coming in at last.

If the modals still don’t work, please share your Bootstrap version details.
