Manual:$wgOOUIEditPage

Note
$wgOOUIEditPage was removed in MediaWiki 1.30, as it is now the default. This was documented as a temporary variable during the migration period.

Details
The edit form since MediaWiki 1.29 uses pretty OOjs UI buttons, checkboxes and summary input. Because this change can cause problems for extensions and on-wiki scripts depending on the exact HTML, the old version is still available in MediaWiki 1.29 and can be used by setting  in.

To make testing easier, users can also force either mode by adding  or   to the   URL.
