Update from 0.4.4 to 0.5.4


i’m using piwik for month now, and i’m very happy with it.
today i saw that a update is available and i tried to do this.

first no errors occured, but then he told me to update the database.

when i click on upgrade piwik the following error occurs:

Critical Error during the update process:
Error trying to execute the query ‘CREATE INDEX index_type_hash ON piwik_log_action (type, hash);’.
The error was: SQLSTATE[42000]: Syntax error or access violation: 1044 Access denied for user ‘censored’@‘localhost’ to database ‘censored

on the server the version 4.1.15 of mysql is installed

please help me to update piwik

thank you, schurl

Ask your admin to grant you INDEX privilege or run the query for you: ‘CREATE INDEX index_type_hash ON piwik_log_action (type, hash);’.

Then continue the update.

i will contact the admin, thanks for your answer!
