check theme compatibility

Definitely a bug. I just did the check and it says the same for me.

Fortunately, NextGen works just fine for me.

Try it out, and you probably won’t have any problems.

i’ve NO problem, i was only wondering why…

A quick check reveals that NextGen uses this code to check for the presence of <?php wp_head(); ?> after loading a page:

// Check to see if we found the existence of wp_head
		if ( ! strstr( $html, '<!--wp_head-->' ) )
			die('Missing the call to wp_head() in your theme, contact the theme author');
		// Check to see if we found the existence of wp_footer
		if ( ! strstr( $html, '<!--wp_footer-->' ) )
			die('Missing the call to wp_footer() in your theme, contact the theme author');

It assumes that wp_head() will insert an HTML comment <!–wp_head–> when it is run, which may have been the case, but is no longer the case.

Again, don’t worry. It will work perfectly fine.
