After installing the quicksell package I am getting an error when trying to access the config page. The same error is popping up when accessing some non-quicksell admin pages.
The error is
406 Not acceptable
An appropriate representation of the requested resource /myinstalldirectory/administrator/index.php could not be found on this server.
This was never an issue before quicksell was installed.
I want to get this working ASAP, so some quick support would be appreciated.
