Thread:Project:Support desk/Some edits not saving, is there some anti-spam feature preventing this?/reply (2)

Latest MediaWiki, no extensions, settings changed to simple private. Fairly standard hosting setup with latest mySQL, PHP5, etc.

No error messages. The times when it's not saving edits I get taken back to the Main page. When edits work I get the little "Edit saved" message popup, and taken back to the page I was editting.
