Check out the official documentation for working with comments in WordPress here.
To turn off comments completely, you will need to disable commenting under Settings > Discussion.
To turn off comments for single posts or pages, click on Screen Options in the upper-right and ensure the Discussion box is checked.
Scroll to the bottom of the page and uncheck Allow Comments and Allow Trackbacks under the Discussion box:
There are a few 3rd Party Plugins you may install to manage disabling of comments on all pages, all posts or specific post types. You can find them by going to Plugins > Add New and search for Disable Comments. Review the available plugins for an updated one that will do what you want.
To create a contact form as seen on our theme demos, you will need to download a Contact form widget. There are several to choose from, each with different features. We are using Contact Form 7, which has been around a long time and is actively supported by its developer.
- You can download the plugin by clicking Plugins on the left-hand admin menu, and choosing Add New.
- Search for Contact Form to view your options.
- To learn more about a plugin, click the Details link, otherwise click Install next to Contact Form 7.
- To create your Contact page, simply create a new page using the Default or Full Width template and add the Contact form shortcode.
When you want a page to be full width (i.e with no sidebar) then you need to do the following:
- Go to Pages > Add New
- Add your title and content
- Select the Full Width option which is on the right hand side under Page Attributes → Template.
- Press Publish
How do I get my full width page to show on the site?
Make sure you have added your full width page to the WordPress menu. If you have done so then it will appear on your site in the menu section.
- Go to Settings > Permalinks
- Ensure anything other than Default is selected
- Click Save
WordPress dynamically generates URLs for your content based on the setting you choose on the Permalinks page. Permalinks are both more semantic and search-engine friendly, but they are not the REAL URL to your content. While WordPress will regenerate permalinks on its own from time to time, you must manually regenerate them by resaving your settings when working with custom post types such as Portfolios or Galleries, after activating a new theme, importing old content, or setting up a new plugin.
