Thread:Extension talk:WYSIWYG/Patch for MW 1.19/reply (39)

I understand your problems being a system admin guy as I'm also working in the same. Your error says that your trying to load ext.wysiwyg.core module but haven't registered it properly before trying to load. I'll suggest you to check $wgResourceModules['ext.wysiwyg.core'] in CKeditor.body.php. It should have all scripts registered with Mediawiki Resource Loader. But if it didn't solve your problem attach a small screen shot of firebug console with errors. It'll help me and I'll try to reproduce the same on my machine.
