Hi there, Sherry
Even though i’m not from Shufflehound team ;-), i’m also using Maskitto Light with quite a bit customization, so maybe i can help you. Let’s see:
1.- “Read more” issue: there’s a lot of guessing here, but it seems that you don’t have a blog page defined in your wp settings. If you check the different posts url’s, you will see that all of them are something like “https://sherryviray.com/post1″, https://sherryviray.com/post2”, etc (i.e., https://sherryviray.com/thankful-on-veterans-day/), as if they are independent pages, instead of posts from a proper blog page containing them. So, when you first created your very first post somehow it became the reference url for your blog front page, that’s “https://sherryviray.com/trek-in-my-head/”, this is the actual url defined for your blog page (also, this post “trek-in-my-head” now seems to be deleted, check september archived posts page -first posts available-, it only shows october posts, no posts at all from september), when it should be something like https://sherryviray.com/blog, so the posts url’s should also look something like https://sherryviray.com/blog/post1/, https://sherryviray.com/blog/post2/ (i.e. https://sherryviray.com/blog/trek-in-my-head/). Following this kinda internal logic, the “Read more” button takes url of the oldest post published in your blog front page (set to show 6 posts within the widget settings), which is the one posted on November 3, 2016, “As the City Sleeps”.
The solution: in the wordpress dashboard, go to the side main menu, settings>reading, where you should already have selected the “static page” option, as it seems to be from your web site look, and then select a page to be your blog page, ideally you should already have a page called blog, if not you can easily create one named so, or choose any other you want from the existing ones. Once changes are saved, your blog url should look https://sherryviray.com/your-chosen-page, and your posts https://sherryviray.com/your-chosen-page/post1/, etc. Maybe you already chose a blog page at the beginning, and this page was deleted, or the page slug changed causing it to be unreachable, or… several things could happened if this is the case, so the best way is to newly define a blog page again. Once you have your new blog page set, you can go editing this blog page and style it through the “page settings” section as usual. There, checking the “show read more button” option should result in correctly loading the rest of the posts within your blog page. The button link should point now to https://sherryviray.com/your-chosen-page, not to a single post.
2.- The “All category” issue: once you have corrected the above issue, this one is also fixed, right now the “all” link points to the only post available in the particular post page loaded (guess it should point again to the oldest one posted if there were more than one post, but you have disabled the category switch in the blog front page), so after the fixing it should point to https://sherryviray.com/your-chosen-page, showing all your posts (all your categories).
3.- The comments issue: this is the easiest one ?? You can choose between a comments deactivation for the whole web site and for a particular page. For a general deactivation, go to wp dashboard>side menu>settings>comments and uncheck “allow comments in new posts” (or something similar, i’m actually using a dashboard in other language than English). Disabling comments in particular pages or posts is also easy: when editing the page/post, open the “screen options” tab right under the admin bar, at the top of the page, and make sure the “discussion” and/or “comments” options are checked. Then you will see both sections in the body of the editing screen for the page/post, tipically under the editor and other sections (depending on which plugins you have running or the theme functions), and make the necessary changes to disable comments. Another easiest way is the quick edit function available in the dashboard>side menu>pages, which lists all your pages, and as you surely know, when hovering any page name this option will show, select it and within the little edit window you will find an option to disable comments for that particular page.
Finally, as a general advise, i recommend you to clear your installation up from all pages and post once rejected, delete everything you are not using no more, tipically pages or posts types from Maskitto demo, and check both page and post slugs and links, to avoid missing links and wrong performance, as with the Load more button or the blog post-url.
I hope all this will be useful, despite there is some guessing in the way.
