No, the added JS doesn’t have any effect. As soon as I click SAVE below the Our Team widget on the WordPress Widget page, backslashes appear before each quotation mark in the widget itself on the WordPress Widget page, even before I go to view the home page on the site.
In the plugin interface, I selected to add the JS through wp_head (choices given are: shortcode, wp_head and wp_footer). I did not copy the JS code to anywhere else – only into the custom css js php plugin page (Add JS). And here is the exact code I put in there:
var $ = jQuery,
targets = $('.our-team .position');
targets.each(function() {
$(this).html($(this).text());
});
And finally, per your last instruction, I cleared the cache, deactivated the plugin, cleared the cache again, then activated the plugin.
