Hello! I just started using your plugin and love it!
I did experience a problem with the plugin positioning when using the shortcode, the plugin would display above the content no matter where I put the shortcode.
I did a little hacking at line 439 on upzSlider.php and found that this fixed the problem:
ob_start(); include(WP_CONTENT_DIR .'/plugins/unpointzero-slider/Slider.php'); $output_string = ob_get_contents(); ob_end_clean(); return $output_string;
I came to this solution from this post: http://wordpress.org/support/topic/plugin-called-via-shortcode-appears-at-the-wrong-place-on-post?replies=5.
Anyway, thanks for the great work!
