Moving Items.php to custom/core and custom/modules make the commands available again...
But now any request to the bot such as
/tell <botname> !items gaze of set
return always the same result:
<Botname> Sorry, your search 'gaze of set' didn't give any result.
I did step-by-step the info getrix sent for accessing the itemDB 3 times but with no result at all.
Any hint ?
