Thread:Extension talk:WYSIWYG/WYSIWYG-CKEditor extension causes "edit" page to load blank

Tried to install the extension and the wiki loads fine, but when you click on "Edit" on a page, the edit page loads blank. If I disable the extension in LocalSettings.php, then I can edit (without the editor of course) but reenabling it causes the issue again.

The wiki is installed at /var/lib/mediawiki and the extension is at /var/lib/mediawiki/extensions/WYSIWYG/WYSIWYG.php
