Advance LayerSlider

I cannot make the advancer lay slider work or a plugin call Master Slider to run in WordPress. When installed the preview runs correctly. However then the slider is used on the site as a widget, a short code or through the theme and the sliders spot is either blank or the the slider is somewhat load like the background or a slide or two but not the whole slide. I tried the slide that came with the theme and a new paid plugin and had the same result. I also tried a pre-made page and a pre-made slide and the same non-active slider error happen. I called a wordpress techy and them still claimed it was a theme issue and not a wordpress setting issue. Everything was working fine. I did try to resort an old back up too from when I new it was working and the issue still was occurring. I have tried disabling all plugin (s) and all the other items I found to do online and nothing seems to be working.
