There’s no way a screen shot is going to show that.
It’s plain and simple:

Go to change avatar. Select avatar and it does nothing. No change, and when save, still no change.

Would BuddyPress work with this plugin?

Okay, I’ve read several of these posts, and found the same thing lacking in them all. A complete misunderstanding of what the people mean.

The blavatar, is on the LEFT site of the admin bar, and is not related to changing the favicon.

Multisites also use it, in front of each site name in the admin bar.

There’s css and code for this:

CSS

#wpadminbar .quicklinks li .blavatar {
	float: left;
	font: normal 16px/1 'dashicons' !important;
	speak: none;
	-webkit-font-smoothing: antialiased;
	-moz-osx-font-smoothing: grayscale;
	color: #eee;
}

#wpadminbar .quicklinks li a:hover .blavatar {
	color: #45bbe6;
}

#wpadminbar .quicklinks li .blavatar:before {
	content: '\f120';
	height: 16px;
	width: 16px;
	display: inline-block;
	margin: 6px 8px 0 -2px;
}

CODE

$blavatar = '<div class="blavatar"></div>';

		$blogname = $blog->blogname;

		if ( ! $blogname ) {
			$blogname = preg_replace( '#^(https?://)?(www.)?#', '', get_home_url() );
		}

		$menu_id  = 'blog-' . $blog->userblog_id;

		$wp_admin_bar->add_menu( array(
			'parent'    => 'my-sites-list',
			'id'        => $menu_id,
			'title'     => $blavatar . $blogname,
			'href'      => admin_url(),
		) );

Also, I found that no one can log in or register, if it’s enabled.
How do I use this, and allow people to register and log in?

Looks like you may have done something that had an effect on the template.

Go to the theme’s settings, and make sure all is as it should be. Sometimes, you may need to check in the editor, to see if any plugins changed anything that did not get undone when disable them.

That may be the infamous white-screen-of-death that happens with some hosts.

The issue appears to be that – when a page is loaded and the script tries to load one (or more) additional files to perform sub-tasks, the system runs out of allocated memory.

The reason this is happening is because those of you encountering this issue are very likely running your site on an overselling host.
This means that the host you chose sells sites with “unlimited” stuff (bandwidth, disk space, etc.) The truth is: No one could actually afford to sell “unlimited” everything (or anything). Hosts need to pay for expenses and make money… The host that you chose may ADVERTISE “unlimited”, but in reality, they have severely limited your account, because they stuff far too many “unlimited” accounts on the same physical or virtual machine. They then apply “hidden” limits and shut you down when your usage exceeds these limits (even though you’re supposed to be unlimited, you’re not).

In this case, there is a limit to how much memory a given script can access. Now, don’t get me wrong… every host has a limit like this. A REAL host, however, has a reasonable amount and will not put far too many accounts on a single server such that they overuse the available resources and they will discuss how much you need if you truly need to exceed that amount.

In your case, the host has set this limit low. You now have two choices.
1- ask your host to increase your available memory.
2- switch to a non-overselling host.
These hosts may be slightly more expensive than the one that you originally chose, but, as is often the case, you do get what you pay for.

Disable all the plugins you added, then enable one at a time and check to see which causes the issue.

Do you have access to phpmyadmin for the site’s database?
If so, can go into there, and go into the wp_options table.
Look for: siteurl & home and make sure both are set to your main site url. That should get you back in.

Any errors in your error log?
Check in your hosting control panel for the error log.
That may help you find the issue.

If this just started recently, it could be due to a limit or software update by your web host. What host are you using? You may wish to contact them, and explain this issue to them.

You may want to look in the css file for the theme.
Usually, sizes for images are handled by the css.

In settings, have you made sure both urls for the site are correct?

Also, make sure all the settings for the gallery are set right, maybe there is a url setting in there, too.

<div style="text-align:right">
<label class="screen-reader-text" for="s"></label>
<input id="s" type="text" name="s" value="search here...">
</div>

That may be good area to start.
You would have to insert the image where you want it in that area.
More than likely after the input tag, before the div closing.

However, you may need to make a div inside to put the image, and make a CSS class for it, so you use css to move it exactly where you want it.
