Maskitto Light uses custom post types i.e. elements that are not WordPress defaults. So, when you use the built-in preview function, WordPress will not know how to display them properly. Luckily, pages (and posts) know how to do that since the theme made widgets for this purpose. Given that, what you should do is to create a page (or post) that will contain the testimonial.
If I read that correctly, you want one testimonial per page, right? This will be a bit repetitive, but it is the only way to go as far as I know.
A. Creating Groups
- Go to Testimonials.
- Edit any of the entries.
- On the right-hand pane, at the very bottom, click + Add New Group.
- Input a name for the group and click Add New Group. I suggest using numbers (e.g. 1) since you will be repeating this for each testimonial you want displayed.
- Finally, click Update.
Repeat the process as many times as necessary. If you have, say, 5 testimonials, you would end up with 5 groups, named 1, 2, 3, 4, and 5 respectively, each only associated with one testimonial.
B. Creating Pages
- Go to Pages > Add New.
- Input an appropriate title as this will be visible in the tab title. You may also want a canned slug for uniformity e.g.
testimonial-1.
- Click the Page Builder tab.
- Select Add Widget > Maskitto: Testimonials.
- Hover over the Maskitto: Testimonials box and click Edit.
- Under Widget group, assign a group e.g. 1. As you can tell by now, each group will need to belong to exactly one unique page.
- You may choose to fill out the other fields. Click Done once you are satisfied.
- Click Publish.
- Visit the permalink.
You should now be able to achieve what you wanted. Similarly, repeat the process as many times as necessary, assigning one group to only one page.
As I stated, posts are also capable of doing this, but the posts you create will also appear in the blog feed proper (which may not be desirable) unless you do a custom query. On the other hand, using posts can neatly categorize testimonials (e.g. https://www.urbanreiver.co.uk/category/testimonials). If you decide to go with the aforementioned, you can do the same steps but for posts instead of pages. Remember to use the correct category for each post you create.
