Please make sure your 'index.php' is up-to-date. In 1.3, it should have the line that includes "libs/upgradephp/upgrade.php".

If you're using any 3rd party plugins, look for an update. For example, GeoIP was updated.

Thanks for your prompt response.

I've updated to the latest version of index.php and it doesn't appear to have made any difference as the same error message appears.

Please check the file permissions and contents of libs/upgradephp/upgrade.php.

It looks like you're making changes and/or doing some other troubleshooting. For piwik.php, I see you've enabled debugging and that your database user no longer has access to the database.

INSERT command denied to user 'dbo364330341'@'212.227.29.41' for table 'piwik_option'

I've changed the file permission to 777 and still no joy. Not sure I understand what the problem is here as I've not made any changes to the script, it just seems to have stopped working for no apparent reason.

Check your web server error log to see if there are more clues.

Otherwise, if you can, send us email (or PM on the forum) with your ftp login, and we'll take a look.

I replaced your index.php because it wasn't the file we packaged with 1.3.

I replaced your piwik.php, turning off the debug.

I suggest your change your ftp password because you posted it here in public. (oops)

The only thing you have to do is either:

• grant privileges to the database user, or
• edit config/config.ini.php, and change the database connection information to a user that has sufficient privileges.

Hurrah, Piwik is back!

Thank you so much for sorting that out, and pointing out that posting your password on a public forum is not a great idea :o)
