Hello

Which version of MD Slider are you using? You please send us your website url to check

Hello,

You site uses many different jQuery versions. For example, header : http://prntscr.com/mf4do0 and footer : http://prntscr.com/mf4enp

This causes problem with jQuery easing load, lacking of effect: http://prntscr.com/mf4a3s.

We try to remove 2 file jquery at footer, and there is no problem with jQuery easing: http://prntscr.com/mf4c7o

Solution:

+ Just use only 1 jquery version at header or footer

+ If you use jquery at header, you do not need to change md-slider. If you use jquery at footer, you please modify module md-slider like this: http://prntscr.com/mf4li9

Hello

We have just resumed our service after Tet holiday. Regarding your questions, you can follow these solutions:

- Method 1: Use jquery 1.10.2 at header: Open your folder theme elos and search code add files: jquery.js , jquery-1.js, then remove or comment those code.
- Method 2: Use default theme's jquery at footer: Edit function add js of our md-slider  https://prnt.sc/mf4li9 so that Md slider adds js => scope footer.
Ex:    

/add js file to footer
drupal_add_js('js file link', array('scope' => 'footer'));
