This is what I am calling:

<umbraco:Macro ItemCount="2" Small="1" Alias="uBlogsyListPosts" runat="server"></umbraco:Macro>

And the .cshtml file is this (again, this was working before) ... 1106 is the landing node for my blog:

// get all posts
   
    
    var landing = new DynamicNode(1106).Parent.GetChildrenAsList.Items.Where(x => x.NodeTypeAlias == "uBlogsyLanding").Single();
    IEnumerable<DynamicNode> postList = uBlogsy.Web.Helpers.NodeHelper.GetPosts(1106);
    
    // get item count
    int count = int.Parse(@Parameter.ItemCount);

    IEnumerable<DynamicNode> nodes;

    if (@Parameter.Small == "1")
    {
        nodes = postList.Take(count);
        <div class="uBlogsy_posts_container uBlogsy_bottom_border">
       
            <ul>
                @foreach (DynamicNode n in nodes)
                {
                    <li>
                        <a href="@n.Url">
                            <span>@n.GetProperty("uBlogsyContentTitle").Value</span>
                        </a>
                       @* - <span>@n.GetProperty("uBlogsyPostDate").Value.FormatDateTimeOrdinal("d MMMM yyyy")</span>*@
                    </li>
                }
            </ul>
        </div>
    }
    else
    {
        // get tag, category, or author from query string
        var tag = Request.QueryString["tag"];
        var category = Request.QueryString["category"];
        var author = Request.QueryString["author"];
        var searchTerm = Request.QueryString["search"];

        nodes = NodeHelper.GetPosts(tag, category, author, searchTerm, postList).Take(count).ToList();
        
        if (!string.IsNullOrEmpty(searchTerm))
        {
            <script type="text/javascript">
                $(document).ready(function () {
                    $('.uBlogsy_content_body').hide();
                });
            </script>
            <h3>@nodes.Count() Results: </h3>
        }
         foreach (DynamicNode n in nodes)
         {
               @RenderPage("/macroScripts/uBlogsyShowPost.cshtml", n.Id)
         }
    }
 }

hard to say

try deleting everything in the macro script to see if it still errors

if it doesnt, then start adding stuff back until you figure out the line

is working on a reply...
