You can change the cookie prefix temporarily or cookie expiration time. Doing this will log out all users though. CP->Primary Settings->Advanced, its at the bottom.
No i need to log out those as and when.
If i had to do it for all, they would get pretty annoyed as half probably cant rememeber there login details anyway. lol
Even if i have to go via the Database i dont mind but its something i need to do, with my forum trouble makers and multiple accounts is now a problem. And showing the software's limitations. Or how we need more control over users accounts.
They dont like notifying as its a one way street and think its always being ignored.
Any other way to force a user to log out ?
even if its at there next click. Page change.
Next submit :
Just something so the new group kicks in.
so if they didnt even have to log out would be better, but its the only way i know at the moment to make the account update to user groups.
