Bootstrap Modal popping up but has a "tinted" page and can't interact

Ok, so I figured out the issue.

If the modal container has a fixed position or is within an element with fixed position this behavior will occur.

Easiest way is to just move the modal div so it is outside any elements with special positioning. One good place might be just before the closing body tag .

This is what I did, and it worked.

This happened to me, and it took ages to diagnose. If it happens to you, add this to your css:

div.modal div.modal-backdrop {
    z-index: 0;
}

EDIT: You may need more specificity for this setting to be picked up. As Nick Spoon suggests, you can use

body.modal-open div.modal-backdrop { 
    z-index: 0; 
}

And you may need to add more qualifiers, depending on what the rest of your CSS is doing. You can also use !important, but that's just sweeping the problem under the rug.

Solved it by adding data-backdrop="false" to the main div as:

<div class="modal fade" data-backdrop="false" tabindex="-1" role="dialog">
  ......
</div>
