Moin, Since a while no new logs a written. (Since last extension update?) I found in the constants: config.tx_piwik { # cat=plugin.tx_piwik; type=input; label= path to piwik piwik_host = typo3conf/piwik/piwik I think it must be typo3conf/piwik/piwik/ (with ending slash) Now piwik works again. Hauke
