As it seems, there is no topic containing the three words calendar & first & blog so I can think this is a new feedback.

ISSUE
no calendar in the "blog1" blog.
Tested with Firefox 3.X, the latest Firefox too, IE6 and IE7

TESTS
I installed several evo sites with several skins, this happens each time. It is not a "default blog" issue but it is related only with the "blog1" blog wich never displays the calendar. If you delete this blog then set another one as default, calendar is well displayed.

REMARKS
I'm no good enough in understanding PHP vey intricated apps but good enough on testing to be sure that this is a kind of bug. I saw something special, that is: 'blog1" is not handled as the other ones are. This appears in Firefox when you try to edit the generated page and have set an external viewer: all the other blogs are displayed using the external tool, the "blog1" blog is displayed with the internal "view source" process. This means that for Firefox "blog1" is not the same than the other blogs.
