Closing Forum, Permanent Archive Mode?

[[ExiTuS]]

First of all, deactivate any activities and deny all actions on users, groups, forums etc.

It would make sense to redirect any request to your website "index.php" directly to "./archive/index.php".
This can be easily done with .htaccess

Of course the Archive Mode needs some more core PHP files, especially "/inc/*".
Archive Mode "/archive/." consists of four files only. Check what files are mandatroy needed for archive, so find all 'require'd files in PHP code and keep these files.

For example:

./archive/index.php:
14: require_once "./global.php";
15: require_once MYBB_ROOT."inc/functions_post.php";

./global.php:
17 require_once dirname(dirname(__FILE__))."/inc/init.php";
18
19 require_once MYBB_ROOT."inc/functions_archive.php";
20 require_once MYBB_ROOT."inc/class_session.php";
21 require_once MYBB_ROOT."inc/class_parser.php";

In these 'require'd files also search for another 'require'd dependencies...
Better use this crossreference to figure out all you need:
https://crossreference.mybb.de/nav.html?index.html

After you know all files 'require'd, the rest can be done.

Note that attachments and smilies must not be deleted.

Good luck!
