That is correct.
My version of sh404SEF is only one version old - need to resubscribe to update and just haven't done it yet.
I just changed the setting to use the Joomla router, cleared the cache, and here's where it directed me:http://www.fredericksburgparent.net/cal ... 13/02/18/-
which is exactly what you predicted. But it's still not a valid page on the site.
But I'm telling sh404SEF to NOT touch JEvents, so it shouldn't be doing anything. I even turned off the SEF radio button the JEvents config yesterday as well.
If you read my very first post, you'll see that everything worked fine until I updated my JEvents to 3.0. Because it broke all my layouts, I had to go back to 2.2.8. That's when everything started to go wrong. Not sure if that helps you diagnose.
