Extension: WikiEditor - index.php is gone


Posted (edited)

Hi Everyone,


I am a new guy try to install mediawiki. and want to install - wysiwyg editor (Wiki Editor) but fail.

I follow the commad as  link -

Add the following code at the bottom of your LocalSettings.php:
wfLoadExtension( 'WikiEditor' );

But after that , I can't access the mediawiki. and show the page does not exist.

If I delete the "wfLoadExtension...." , mediawiki works again.


mediawiki verson:1.27

PHP 7.0.33

and I sure select the right version for WikiEditor.


2019/05/07 update the error screen as below

A blank white page indicates a PHP error, see the How to debug page on mediawiki.org for more information on obtaining the actual error messages. Once you know the error message, if you are having troubles figuring out what it means, post back here and we can help you out.

I notice that you are attempting to load the extension twice in your LocalSettings.php; you have both a require_once for the WikiEditor files as well as wfLoadExtension. You should use either wfLoadExtension or require_once, but never both. Moving forwards, extensions should be loaded via wfLoadExtension, as the require_once method is now deprecated in recent versions of MediaWiki and support for it is being removed.

Finally, your MediaWiki version (1.27) is going to be end of life next month. You should begin plans to migrate to a more recent version if you wish to continue receiving security updates and improvements.

Where did you unpack the WikiEditor files to?

Can you show us your full LocalSettings.php file? Just delete the password first.
