Problem z serverem!

Cześć mógłby mi ktoś pomoc ponieważ mam problem serwem kiedy próbuje napisać skrypt na report lub skrypt typu "json" lub na efekty wirtualne zawsze wyskakuje mi komunikat "An internal error occurred while attempting to perform this command"

Serwer mam na lokalu, dodatki które posiadam to SKQuery, WildSkript, itp...

kod który mi wyskakuje przy włączaniu serwera
