Weird problem, /manager needs to redirect to /manager/

Just installed a subdomain with fresh modx evo 1.0.15. www.new.domain.com/
After installing and save the configuration I get redirected to /manager which needs to be /manager/
I see the page not found instead of the manager ?!!

The default .htaccess is being used. Never had this problem before..
I have no idea whats wrong.

Seems other subdomains on the server now have the same problem. Root main site doesn't.
I did a /flushdns but still no changes.

Anyone a idea what could be wrong?
On other domains and subdomains I can type /manager and then it redirects to /manager/ [ed. note: fourroses666 last edited this post 11 years, 5 months ago.]
