After updating to version 0.6.1 I got the following issues.
On the “Settings” page appear now this message: User ‘anonymous’ doesn’t exist.
I read here in the forum that it is possible to setup an anonymous user directly in the database table piwik_user and the problem is solved but there was no further explanation.
Please, would somebody explain for me how to do this? I am not very familiar with Mysql databases.
Furhter I have noticed that the statistic results after the update first worked well but then after some hours they had an failure about several hours. Now it started to count again, ist that normal?
Figured it out. Do you have phpMyAdmin that you can use to modify your database?
If so, open the piwik_user table and select the Insert tab. Enter anonymous for the user name and click go. That simple.
If not, find out how to get into the piwik database and run the following insert command against it. Replace piwik_db with your database name. Because of the specifics of single quotes, it is best if you copy and paste the following code.
You cannot login with the anonymous user, it is not possible, anonymous means “not logged in”. Instead you should login with your super user login and password. If you forgot your super user login, it can be found in the config/config.ini.php file
Can you check in your Mysql table piwik_site that the column ts_created has a correct value (the date should be the first date of data for your website , ie in 2011 or before)
