Hello, When I try to change the preferences of the OpacHiddenItems system, Koha does not let me save, it indicates an internal error, I want to leave only these: itype: [AUDIOVISUA, COMPUADOR, COMPUTEC, EQUIPOSBIB, INTERBIB, NOVEDAD, MATDIDACT, MATELECTR] location: [ACQUISITION]
Can you save other system preferences? Pleaase check About Koha > System information
A missing lockdir can prevent system prefernces from being saved, so that's why I am asking these questions.
Closing, please reopen with more info if still valid
