I have installed from debian package posted on the website. The initial installation works fine (dotlrn version 2.1.0b3). when I try to upgrade to the version 2.1.3b using the site admin tool teh process completes fine but I can use the site anymore and the following error comes up:
Database operation "select" failed (exception NSDB, "Query was not a statement returning rows.")
ERROR: column does not exists: "hidden_p"
The same thing happens when I choose install instead of upgrade. Thanks in advance for your help,
eric.
