How to move a page
You can quickly move a page with the rename action in the railbar.
The move plugin is based on the search index.
If for any reason such as an index that is not up to date, you got a problem during a move, the plugin can let a lock file at DOKUWIKI_HOME/data/locks_plugin_move.lock.
This file should be deleted, otherwise you may get strange behavior. For instance, the move plugin will not save any of its processing and it will purge the cache each time for locked page.
To prevent any more damage, we don't allow any move if the lock file was created more than 5 minutes ago and we send you a notification.
