I was looking into some of the ascx pages, doing some modifications, and I came across a couple of 'non well formed' lines in /controls/ForumCategoryList.ascx
line 29
</HeaderTemplate>
error: the <table> tag was not close before this </HeaderTemplate> tag
line 56
</table>
error: marked invalid because it is a mismatched end tag
I shuffled things around and got a well formed page:
line 8 (table opening) cut and replace on line 6 (right after <ContentTemplate>)
line 56 (table ending) cut and replace on line 55 (right after </asp:Repeater>)
this encloses the HeaderTemplate and asp:Repeater within the table tags.
Besides now being a 'well formed' document, I found a considerable increase in forum response.
