But when I go to add a new blog page I get a complete different page that doesn't look official at all, maybe a plugin is causing it. Can someone help?
Your first screenshot shows the legacy “Classic Editor”. This was the default post editor in WordPress up until WordPress 5.0 was released on December 6, 2018. WordPress’ default post editor now looks like the one you can experience on [this demo page](https://wordpress.org/gutenberg/). You’ll see it being referenced as “the block editor”, or “Gutenberg” (the code name for the project). If you’d like to use the legacy “Classic Editor” on your site, you can install [the Classic Editor plugin](https://wordpress.org/plugins/classic-editor/).
Your second screenshot shows the HTML view of the default “block” editor I mentioned above. You can switch between the HTML view and the default view by clicking on the 3 dots in the top right corner on the page.
On that screenshot, you can also see an “Edit with Elementor” button in the top left corner. This is because [the Elementor plugin](https://wordpress.org/plugins/elementor/) is installed on your site. Clicking on that button will open yet another post editor, powered by Elementor.
You can try all three and see which one you prefer. It’s worth noting that if the Elementor plugin is already active on your site, it’s possible that several aspects of your site’s design were designed with Elementor by the previous site owner. As a result, deactivating that plugin may cause some layout issues on your site.
