Hi, I found a possible error at staff interface. Home › Administration › System preferences at Administration preferences Login options timeout It read as: Automatically log out users after____ seconds of inactivity. Adding d will specify it in days, e.g. 1d is timeout of one day. In fact it should read as: Automatically log out users after____ milliseconds of inactivity. Adding d will specify it in days, e.g. 1d is timeout of one day. Use milliseconds replace seconds. Refer to Koha manual, please http://manual.koha-community.org/3.4/en/administration.html 1.2.3.5. timeout Automatically log out users after ___ milliseconds of inactivity. Wishing you all the best. . . .
