Probably the Best Free jQuery Slider/Slideshow Plugin for WordPress. Responsive, Settings & Multiple Sliders!
Some hosting set-ups may have this issue. Just give it an empty parameter like so:
// All slides, with empty parameter set to stop warning from appearing <?php echo nextslider_slider_template(''); ?>
Make sure that you’re stating the ID correctly like the examples above. Remember that you can find the slider ID under Slides > Sliders.
If you’ve done everything else right and it’s still not displaying, you’re probably having a jQuery conflict with another plugin/theme. Try reverting back to the default Twenty Eleven or Twenty Twelve theme and disabling each plugin one by one.
Why yes you can!
How sweet of you. Anything from a small donation (made through the Captain Slider settings page) to a link to Captain Theme (http://captaintheme.com/) on your site helps!
