I installed WP Data Tables today and anytime I try to hit apply, delete, or cancel everything freezes and all I can do is hit refresh or close out the page and reopen. I can't really utilize the plugin if I can't actively do anything on it. Any suggestions?

Looking into it deeper, it is the FAQ problem where the edit modal's z-index is too low compared to the modal backdrop, but putting in the CSS you recommended doesn't work, the z-index is still 9999 due to the bootstrap theme. Turning the front-end bootstrap off does not help.

Bogdan,

This is a problem when I'm still on my Wordpress dashboard and trying to delete a table on my wpDataTables page (see attached screenshot). It is a CSS collision with another plugin, Zippy Courses, whose CSS I cannot edit.

The selector from the other plugin is 

#wpbody .modal { z-index: 9999; }

which targets wpDataTables' delete modal accidentally.

Because the selector of your grey modal background

.wpdt-c .modal-backdrop, .modal-backdrop

is also set to a z-index of 9999, the backdrop is over the delete modal causing it to be un-clickable.

I implemented the custom CSS you recommended in your FAQ in wpDataTables > Settings > Custom JS and CSS (see attached screenshot), but the backdrop is still over the delete modal. I tried increasing the z-index of #wpbody .modal {z-index: 10010;}, but that also does not work.

I can work around it by editing Chrome's developer's tools, but this is a problem overall. I cannot remove the other plugin, it is necessary for my business.
