I had a developer make a site for me. so bare with me, im not great at this.
I had a layer slider on my index page, when I updated to the latest version of wordpress the slider stopped working and I got this error.
LayerSlider: old jQuery issue
It looks like you are using an old version (1.12.4) of the jQuery library. LayerSlider requires at least version 1.7.0 or newer. If you are using the WordPress version of LayerSlider, you can try out the “jQuery Updater” plugin from the WP plugin depository. If you don’t know what to do, you can write us a private message from our CodeCanyon profile page. We need a temporary WP admin account (or a temporary FTP account in some cases) to solve this issue.
I did try to us the jquery updater which got part of the slider working, but not the second slide. Also, when I activated the jquery updater, it stopped another script at the bottom of the index page that scrolls threw testimonials.
