Hello Alex,
Go to Core/local.config.php and under Config::Set('SESSION_LOGIN_TIME', (60*60*24*30)); # Expire after 30 days, in seconds around line 143 make sure that this is under it.
/* Days of the Week
The compacted view, and the full text
DON'T CHANGE THE ORDER!! And yes, Sunday is in there twice
*/
Config::Set('DAYS_COMPACT', array('Su', 'M', 'T', 'W', 'Th', 'F', 'S', 'Su'));
Config::Set('DAYS_LONG',
array('Sunday',
'Monday',
'Tuesday',
'Wednesday',
'Thursday',
'Friday',
'Saturday',
'Sunday'
)
);
Hope I could help!
