I don't really consider this a bug, but rather a problem that probably has something to do with some IIS-settings, but still might be a reason to change the bahviour of the calendar to generate different urls. It has worked before and now it suddenly does not on several sites, but since I am not the primary web-administrator for the IIS-server I cannot tell exactly what has changed. Most likely no one has changed any settings about this on purpose, but my guess is that an update to the IIS has modified the URLSCAN filter or something. Can it be the colons in the request for the time according to Swedish settings?
 

Error description:
When going to the calendar and click on the arrows to show next or previous month i get:

HTTP Error 400:0 - Bad Request.
ASP.NET detected invalid characters in the URL

Detailed description shows the following:

What can be wrong and how do i fix it? Very strange that it stops at the
(Cannot upgrade the mojoPortal version at this time.)

I do have the possibility to create a FREB-report if absolutely necessary, but it is a little extra work on the production server.

Great!

Thanks Joe for the quick answer, as always.

Workaround works perfectly (after finding the 301 url-redirect i had made earlier when i changed to extensionless urls.)

I understand what you meant, but the two urls you posted are extremely similar .-)
