Hello Jens

I suppose there's a conflict with some other plugin's Bootstrap.js files. Even if you were to remove all plugin's tables and settings, all this would come back again once you reinstall the plugin.

Perhaps the best thing we can do is log in, and try to change some lines in our code, and see if we can get the plugin to co-exist with the other plugin.

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Thanks Jens, that worked. I got it.

In ../wp-content/plugins/wpdatatables/source/class.wdttools.php, around line 1454 I modified a couple of lines of code:

if (!is_admin() && get_option('wdtIncludeBootstrap') == 1) {
            wp_enqueue_script('wdt-bootstrap', WDT_JS_PATH . 'bootstrap/bootstrap.min.js', array('jquery', 'wdt-bootstrap-select'), WDT_CURRENT_VERSION, true);
        } else if (is_admin() && get_option('wdtIncludeBootstrapBackEnd') == 1) {
//             wp_enqueue_script('wdt-bootstrap', WDT_JS_PATH . 'bootstrap/bootstrap.min.js', array('jquery', 'wdt-bootstrap-select'), WDT_CURRENT_VERSION, true);
        } else {
//             wp_enqueue_script('wdt-bootstrap', WDT_JS_PATH . 'bootstrap/noconf.bootstrap.min.js', array('jquery', 'wdt-bootstrap-select'), WDT_CURRENT_VERSION, true);
            wp_enqueue_script('wdt-bootstrap', WDT_JS_PATH . 'bootstrap/bootstrap.min.js', array('jquery', 'wdt-bootstrap-select'), WDT_CURRENT_VERSION, true);
        }

Basically, I commented the two lines, and added one line below the second commented line, and now everything should be working normally.

Please check and let me know.

You're welcome, Jens

Hello again Jens

It seems like you're having some caching issues. wpDataTables isn't being cached, and this happens only for server-side tables.

My advice is to prevent caching for this entire page, or wpDataTables files on that page (if possible to selectively exclude files from a page).
