Admin Interface

I have to log in to every page

This indicates that your browser is not getting or accepting the session cookie for some reason. The cause can be several things:

  1. There could be an error message coming from PHP before it sends the "Cookie" header back. Look at the source of the page, or in the webserver error log for clues. Take care not to add any new line characters after ?> in the config file in /etc/davical/*-conf.php!
  2. Your browser might be rejecting the cookie. Check in the privacy settings for your browser that it allows the cookie.


I get a blank page

May your PHP installation is configured to interpret scripts only in a directory for web contents (i.e. /var/www) - what is totally good - and you have forgotten this or never knew about it.

To solve this problem, you must allow PHP to interpret scripts from davical and awl. To do so, just add the following line to a .htaccess file in /usr/share/davical/htdocs or to your VirtualHost configuration: 

php_admin_value open_basedir /usr/share/davical:/usr/share/awl/inc:/etc/davical

Note: Some sites mistakenly represent that 'open_basedir "1"' is sufficient. It is not, and is frequently the cause of this problem!

Authentication

HTTP authentications fails on me

It seems the username for HTTP-auth needs to be lowercase, even though the username in the admin interface contains uppercase letters. See also this bug report.

DB Errors During Upgrade

Permission Denied errors during Upgrade

Check that you're not facing this Issues/Wrong table owner.

Upgrading from Debian Lenny to Squeeze

If you get blank pages from the server and HTTP 500 errors in the access log but nothing in the error.log after an upgrade from Debian Lenny to Squeeze, check the php_value entries in the virtual host, as the format seems to have changed. The new entries have to look like: 

php_value include_path /usr/share/awl/inc
php_flag magic_quotes_gpc off
php_flag register_globals off
php_value error_reporting "E_ALL & ~E_NOTICE"
php_value default_charset "utf-8"
