Error message after successfully deleting a repeatable region in Blog.

OK, did that, threw a bunch of warnings about duplications etc. but that seems to have fixed that error being thrown when deleting a repeatable region.

Thanks, Stuart.

This was a repeatable region inside the blog post template for an image gallery with titles/links etc.

<perch:repeater id="gallery" label="Gallery">
                    <li class="slide">
