Ok thank you for the all required information and I know now the redirection happens because of the following code you added to select the taxonomy terms:
jQuery( document ).ready(function() {
jQuery('.wpv-filter-form input[name="wpv-success-story-category[]"][value="fibromyalgia"]').prop('checked', true);
jQuery('.wpv-filter-form input[name="wpv-success-story-category[]"][value="pain"]').prop('checked', true);
jQuery('.wpv-filter-form input[name="wpv-success-story-category[]"][value="back-body-pain"]').prop('checked', true);
jQuery('.wpv-filter-form input[name="wpv-success-story-category[]"][value="fatigue"]').prop('checked', true).trigger('change');
});
(I've commented the above code for now, if you want you can uncomment it, The above code is responsible as you can see that page is redirected after some time with some URL parameters and view reloads).
Now, I would like to know how exactly you want to filter the view. Lets say view is loaded first time so it should be filter the results by default with the terms fibromyalgia, pain, back-body-pain, fatigue.
Now, further when user interact with taxonomy filter how you want the result should be filtered. Do you want to always filter results with terms fibromyalgia, pain, back-body-pain, fatigue even user select other terms or the view results should be filtered with terms fibromyalgia, pain, back-body-pain, fatigue and then when user select other terms all default terms should be excluded?
Regarding the redirection issue when you click "read more" I can see the issue but as its a live/production site I will require duplicator copy of your site in order to debug that issue further. When we click on "read more" button the URL is redirected to single "success-story" post but somehow it does not load the assigned content template but the same page from where we clicked on the "read more" button.
It seems any plugin or theme hijacks' the single post URL or possibly cache. But I could tell more when I further debug that and to do so I will require duplicator copy of your site. Will you be able to send me duplicator copy of your site or if you agree I can install the duplicator plugin on your site and download it.
