i see no option for this plugin to cause that issue. better try the other plugin’s support

Not really the functionality of this plugin but you can do that with this simple jQuery snippet

add_action('admin_footer-post-new.php','limit_category_selection_count');
add_action('admin_footer-post.php','limit_category_selection_count');
function limit_category_selection_count(){
	$limit = 2; //change this to the number you want to limit
	?>
	<script type="text/javascript">
	jQuery(document).ready(function($){
		$("input[type=checkbox][name^='post_category']").click(function() {
		    var bol = $("input[type=checkbox][name^='post_category']:checked").length >= <?pphp echo $limit; ?>;
		    $("input[type=checkbox][name^='post_category']").not(":checked").attr("disabled",bol);
		});
	});
	</script>
	<?php
}

what theme are you using?

Thanks, Fixed in 1.9.8

sadly its not going to be fixed on this plugin’s end.

Don’t know what the issue but when i tried to activate that plugin i got

“The plugin generated 53291 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
“

and two notices

Notice: Undefined variable: theOptions in wp-content\plugins\lightbox-plus\lightboxplus.php on line 260
Notice: Undefined variable: theOptions in wp-content\plugins\lightbox-plus\lightboxplus.php on line 261

which would lead me to suggest using another plugin.

look for javascript errors, and let me know.
