Addons are custom features that you can add to your Vanilla forum. Addons are created by our community of developers and people like you!
These addons are for people who downloaded and set up their own Vanilla forum. Compare your downloaded version with the version requirements on the right.
If your Vanilla forum is hosted at VanillaForums.com, this addon may already be installed there.
UnsureThe community has said nothing.
When you enable this plugin it will allow you to "close" your forum as you upgrade or make changes. You can customize closed.php to be whatever you want to be shown.
If you have any issues with redirect change line header to redirect to direct path ie: 'http://pathtovanilla/plugins/Maintenance/closed.php' ;
Now when in Maintenance mode, a bar will show to remind you to turn off the plugin. When you disable the plugin, visitors can access the site again.
Note: I recommend you use this plugin instead: https://vanillaforums.org/addon/1299/admin-mode instead.
