Anyone else getting this error?

I am updating with hotfix in a few minutes. I will see if this error comes back. The message sends fine, the error message is just annoying.

Nah still occurring, will look into it, but if anyone knows anything feel free to chime in.

This is just too funny, replying to my own messages. I think I found out what the problem was.

So far it has not happened again.

I saw that J!1.5 was redirecting to itemid=66 (which might be different for others and probably is). This was a link on my usermenu "Private Message" that links to the uddeIM inbox.

I had it unpublished, so when it tried to redirect to the unpublished link of course router.php didn't find such a link hence the error
