Ok, I'm trying to enable the SQL2Wiki extension. One of the steps is to add
require_once("$IP/extensions/SQL2Wiki/SQL2Wiki.php");
to the bottom of of my LocalSettings.php.
When I put it in exactly how it's above then refresh my wiki, it takes the whole webpage for SQL2Wiki and injects it into every page of my Wiki.
I then tried changing the line
require_once("$IP/extensions/SQL2Wiki/SQL2Wiki.php");
to
require_once("/full/path/to/file/SQL2Wiki/SQL2Wiki.php");
and immediately after that, it just broke the whole wiki page so I just got a page cannot be displayed. I removed the line and the whole wiki works fine.
I can't do this trial and error too much. This is an enterprise wiki. I'm not sure how many people really use the wiki now, but I'd really like to get this feature to work.
