[CMS] CMS Error when saving an article

[rnenni]

Hello,

When I save an article, I get this error message:

Warning: Missing argument 1 for special_threaddata_postsave(), called in [path]/includes/class_dm_threadpost.php(1507) : eval()'d code on line 2 and defined in [path]/vault/plugins/data/thread.php on line 105

And the article does not get saved. What does this mean and how can I fix it?

This is a problem with a third-party addon - looking at the error message, I am guessing it is from VaultWiki. You'll need disable the addon or ask over at vBulletin.org for help with this.
