Hey,
Noticed this on our portal.itflow.org instance too, seems we missed that 🙁
The obvious workaround for now would be to temporarily disable the feature in admin settings. Alternatively, reconfigure your apache vhost to redirect /portal
to /client
RewriteEngine On
RewriteRule ^/portal$ /client [R=301,L]
There will likely be other issues with the release, so I'd like to catch those in any sort of hotfix.
