When I go to the provided link, I do not have access to the contact form until I sign in using my WordPress.com account. When I sign in, it takes me right back to the initial page you linked, telling me to sign into my account.

Your welcome, glad I could help ??

Looks like you may need to increase the width of the .entry-content. I found the following CSS:

@media screen and (min-width: 61.5625em)
body:not(.search-results) article:not(.type-page) .entry-content {
    float: right;
    width: 71.42857144%;
}

Perhaps if you changed it to this:

@media screen and (min-width: 61.5625em)
body:not(.search-results) article:not(.type-page) .entry-content {
    float: right;
    width: 100%;
}

@kazookie,

You should probably not be so concerned about a particular screen size, since a browser width/height is variable. Recently the mobile first/responsive approach has become popular, and you may want to read into it. Other than that, I would just base my design off a popular device or desktop size, using percentages, and media queries to make it responsive. There are many popular grid systems available as well, based off common desktop screen sizes. Using your browsers developer tools, you can probably find common dimensions for mobile devices.

Looks like it is already possible, you just need a bigger image. If you featured images or being cropped too small, check out this codex page on how to edit them.

This may center your featured image:

.entry-content >img {
    vertical-align: middle;
    margin: 0 auto;
    display: flex;
}

This should get your featured image to the top:

.entry-content {
    margin: 0;
}

.content-left-wrap {
    padding-top: 0px;
}

Remove the .main-inner class from your css selector.

Primary Sidebar CSS:
/* set full primary sidebar background */
.s1 {
background: #f3fbc4 !important;
}

Looks like it is still there, just no background color. You can use your browsers to inspect the menu and add the necessary css. I could see it after entering this:

ul#menu-primary-menu {
    background-color: grey;
}

You will probably want to position it elsewhere however.

I found this article for you on the subject that may be helpful.

I think you need to use a higher resolution image. If cropping, this may be causing the issue if the original image is large enough.

@autori76, this prior post might be relevant to your situation.

@autori76, Perhaps this codex page on changing file permissions will help?

Im thinking it could be an issue with the css or page template. I believe the forum rules need you to ask your question to the theme developer for premium themes, in this case likely studiopress.

The ignore file on the GitHub repository was blocking the images directory. I have updated it to include it on there if that helps.
