site maintenance - how i can?

[mikeh]

i use Getsimple 3.0

i tried to use this plugin
Maintenance
http://get-simple.info/extend/plugin/maintenance/29/

but doesn't work (if i choose to enable "site maintenance" by check-box in admin panel, when i save new option the check-box comes back again empty)

is there another solution for a "site maintenance"?

You can always make a backup of the root "index.php". Then just create a new index.php with whatever the maintenance message should say. Then were the maintenance is complete, replace the old file

yes.i tought this solution ....but then all other pages are avaible?!?!?

Actually it would do the opposite. it will kill all pages
