In folder 'test' I have created an 'acl_users' folder with userid of 'testuser'. There's the sample index.html that get's created along with the folder. 'testuser' can see this fine. I then proceed to create a ZSQL method, connecting to my Postgres7.4 database with ZPsycopg. The sql method works fine as superuser. However, when 'testuser' attempts to use the sql method, I get: Site Error An error was encountered while publishing this resource. KeyError Sorry, a site error occurred.
