Single page slug with 'hyphen'
Can anyone think of a good way around this? Single pages don't seem to support canonical URLs like template pages do.
The only way around this is to look into your database and the "PagePaths" table from there. If you change the single page's page path from there, it would work through the dashes.
But please not that this workaround can only be used for the single pages you have created yourself! If you modify the URL slug of any core single page, you might possibly break some redirects or hardcoded URLs on that page.
