Problems with Subdirectory Installations
Subdirectory installation (like mydomain.de/somedirectory/fileadmin/...) don't work with the recent version of the cookie optin extension. The path in fileadmin can be changed to fix the issue, but it would be better if this is handled automatically. Also the saving of the configuration is only working if the path is calculated correctly.
