I updated from 1.4 my Piwik to 1.5 using the automatic function.
The installation and the database conversion were OK.
Now I can see this error message “The Piwik configuration file couldn’t be found and you are trying to access a Piwik page.” appearing randomly on some Widgets.
See this print screen : Error Widgets Piwik 1.5
The config.ini.php and global.ini.php files are in the Piwik/config directory and seem to be converted.
How can I, please, fix this problem ?
