Logo, Menu, Fonts Not Updating

Hello,

I'm a bit below average in terms of working on sites. I did a few out of the box wordpress Avada themes in the past, but trying the Elementor + GeneratePress to speed up site performance and take a bit more control. I just downloaded the 2 and am stuck (just have the 2 plugins so I don't believe it's a plugin issue). I tried clearing the cached of Google Chrome. I cannot get any of the following to work properly: menu items won't show up, logo comes up sometimes and is super huge (or gone if I make changes), fonts won't update.

I don't know if its a memory thing or not. Here's the code I have in the default-constants.php:

// Define memory limits.
	if ( ! defined( 'WP_MEMORY_LIMIT' ) ) {
		if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
			define( 'WP_MEMORY_LIMIT', $current_limit );
		} elseif ( is_multisite() ) {
			define( 'WP_MEMORY_LIMIT', '64M' );
		} else {
			define( 'WP_MEMORY_LIMIT', '40M' );
		}
	}

I think I read someone write to change the memory to 128M as well as a link. I didn't understand the link and didn't want to play around with anything. Should I change one of those two numbers? Has anyone used HostGator in the past? Do they limit memory on their end? Is all this that I'm experiencing a common issue? Can I supply a password for someone to look at the backend if it's not a common issue? Sorry for all the questions. Just almost at a give up stage after sitting here for a few hours.
