If you restore the page, all revisions will be restored to the history.
If a new page with the same name has been created since the deletion, the restored revisions will appear in the prior history.

Some parameter types in API requests need further explanation:
;boolean
:Boolean parameters work like HTML checkboxes: if the parameter is specified, regardless of value, it is considered true. For a false value, omit the parameter entirely.
;timestamp
:Timestamps may be specified in several formats. ISO 8601 date and time is recommended. All times are in UTC, any included timezone is ignored.

Title of page the text belongs to. If omitted, <var>$1contentmodel</var> must be specified, and [[API]] will be used as the title.

Parses content and returns parser output.

See the various prop-modules of <kbd>[[Special:ApiHelp/query|action=query]]</kbd> to get information from the current version of a page.

There are several ways to specify the text to parse:
# Specify a page or revision, using <var>$1page</var>, <var>$1pageid</var>, or <var>$1oldid</var>.
# Specify content explicitly, using <var>$1text</var>, <var>$1title</var>, and <var>$1contentmodel</var>.
# Specify only a summary to parse. <var>$1prop</var> should be given an empty value.

Restore link text. Parameters:
* $1 - the number of revisions to be restored

SQLite stores all data in a single file.

The directory you provide must be writable by the webserver during installation.

It should <strong>not</strong> be accessible via the web; this is why we're not putting it where your PHP files are.

The installer will write a <code>.htaccess</code> file along with it, but if that fails someone can gain access to your raw database.
That includes raw user data (email addresses, hashed passwords) as well as deleted revisions and other restricted data on the wiki.

Consider putting the database somewhere else altogether, for example in <code>/var/lib/mediawiki/yourwiki</code>.

To restore the page's entire history, leave all checkboxes deselected and click <strong><em>{{int:undeletebtn}}</em></strong>.
To perform a selective restoration, check the boxes corresponding to the revisions to be restored, and click <strong><em>{{int:undeletebtn}}</em></strong>.

Upload a file, or get the status of pending uploads.

Several methods are available:
* Upload file contents directly, using the <var>$1file</var> parameter.
* Upload the file in pieces, using the <var>$1filesize</var>, <var>$1chunk</var>, and <var>$1offset</var> parameters.
* Have the MediaWiki server fetch a file from a URL, using the <var>$1url</var> parameter.
* Complete an earlier upload that failed due to warnings, using the <var>$1filekey</var> parameter.
Note that the HTTP POST must be done as a file upload (i.e. using <code>multipart/form-data</code>) when sending the <var>$1file</var>.

Text to diff each revision to. Only diffs a limited number of revisions. Overrides <var>$1diffto</var>. If <var>$1section</var> is set, only that section will be diffed against this text.

Details of the error are attached to the report, which will be publicly viewable. If you are not comfortable with that, you can edit the report below and remove all the data you don't want to share.

It is possible to restore all Semantic MediaWiki data based on the current contents of the wiki.
This can be useful to repair broken data or to refresh the data if the internal format has changed due to some software upgrade.
The update is executed page by page and will not be completed immediately.
The following shows if an update is in progress and allows you to start or stop updates (unless this feature was disabled by the site administrator).

Title of the page to which history will be merged. Cannot be used together with <var>$1toid</var>.

Page ID of the page to which history will be merged. Cannot be used together with <var>$1to</var>.

Restore revisions of a deleted page.

A list of deleted revisions (including timestamps) can be retrieved through [[Special:ApiHelp/query+deletedrevs|list=deletedrevs]], and a list of deleted file IDs can be retrieved through [[Special:ApiHelp/query+filearchive|list=filearchive]].

If set, a new entity will be created.
Set this to the type of the entity you want to create.
It is not allowed to have this set when <var>id</var> is also set.

The text to output instead of the list, if the list is empty. If empty, error message will rendered (such as "Page has no subpages to list"). If dash ("-"), result will be completely empty.

This hierarchy cannot be edited because both the hierarchy data and the category from which to draw unused pages are empty. Please ensure that at least one of these data sources is populated.

Restore link text. Parameters:
* $1 is the amount of number to be restored
