No solution yet. It is interesting that we both migrated websites, perhaps that has something to do with it? I used ManageWP’s Clone feature to move an existing website to a staging site where I changed the theme and did some major changes and them Cloned back to the original site. I think the error message appeared after I Cloned to the staging site. It is still there after Cloning back to the original site.

I don’t know why “create_pages” and “create_posts” were disabled for Administrator — I could do both.

Fresh Administrator: I can create a new Administrator user using the WP dashboard, as usual. The NextGEN error message still appears when logged in as that new user.

I’m not sure what happened before I took over this project. Is there a way to create a fresh Administrator role with default capabilities? User Role Editor plugin shows all Administrator capabilities enabled except “create_pages” and “create_posts” — I enabled those and still get the NextGEN msg. The role is listed as “Administrator (administrator)”

Yes, there is an administrator role, and I am logged in as administrator. I installed the User Role Editor plugin to make sure all the NextGen capabilities were check-marked for Admin, and they are (10 of them). (I inherited this site from another administrator.) Website is https://www.thevpc.org

The symptoms were:
Activating the NextGen Gallery plugin caused the homepage slider to disappear. The theme is Asteria. https://relpnc.org

I noticed an error in Firebug console:
$(“ul.main-navigation”).superfish({
TypeError: $ is not a function

Original code in footer.php

<!-- Initialize the Slider, Dropdown Menu and jQuery Tabs -->
<script type="text/javascript">
$(window).load(function() {
	$('#slider').nivoSlider();
});
</script>

<script type="text/javascript">
$("ul.main-navigation").superfish({
		animation: {height:'show'},   // slide-down effect without fade-in
		delay:     1200               // 1.2 second delay on mouseout
	});
</script>

Revised code in footer.php

<!-- Initialize the Slider, Dropdown Menu and jQuery Tabs -->
<script type="text/javascript">
jQuery(document).ready(function($) {
	$(window).load(function() {
		$('#slider').nivoSlider();
	});
});
</script>

<script type="text/javascript">
jQuery(document).ready(function($) {
	$("ul.main-navigation").superfish({
		animation: {height:'show'},   // slide-down effect without fade-in
		delay:     1200               // 1.2 second delay on mouseout
	});
});
</script>

Your theme may be similar.

I have the same issue using the Asteria theme. The Nivo Slider that is embedded in the theme disappears from the home page when I activate NextGen.
