Recently we upgraded our MediaWiki installation from 1.23.5 to 1.26.2.
We were using WYSIWYG MediaWiki extension in our existing version (1.23.5). During upgrade, we copied the same extension to 1.26.2 extensions folder and enabled it in LocalSettings.php.
However it did not worked and we got "500:Internal Server Error" when we tried to "Edit" any MediaWiki Page.
After a bit of research we found that we need to download a new version for this extension from this URL- https://github.com/Mediawiki-wysiwyg/WYSIWYG-CKeditor
Once downloaded, we copied the WYSIWYG folder to our extensions folder and it started working fine.
Hope this helps someone who is facing similar issue.
