In order to turn off the right rail, page title, FB and Like buttons, use the Wiki Factory variable wgMaximizeArticleAreaArticleIds associated with the Wiki you are working on.
The code that will show up under that variable:
0 => 19649,
- The 19649 number is equal to the article ID of the page you want to turn the right rail off on.
- How to find ArticleID: View Page Source and then Command + F for wgArticleId
- If there is already a number, add the 2nd one after the comma and make sure there is a comma after that number, i.e.:
0 => 319828, 333645,
