Hello,
I have created some pages in the (old) Atlas pages and migrated to AJAX
version. After the update I noticed that any page containing ASP.NET
AJAX won't compile anymore. Even if the same tags and properties are
used in a page without a masterpage.
Does anyone shares this exprerience with me or does anyone knows an
answer?
For the time being, I copy-pased the headings in my masterpage to the
