Hi.

I am using commercial Artio booking in Finland.

This text seems not using language files

UNABLE_DISPLAY_RESERVATIONS_MUST_BE_LOGGED_AS_CUSTOMER_OR_ADMIN="Unable display reservations. You must be logged as Customer or Admin."
Changing it in fi-FI.com_booking.ini or even en-GB.com_booking.ini does not affect, it seems to be hardcoded...

Where I can change it in php code?

There is also texi in reservation list that are not translated
Res. # Item QTY OCC

I don't find them also even in en-GB.com_booking.ini -file.

It seems that they are also hardcoded? Where?
