Sorry, your last post confused me. Are you saying that you have another instance of MediaWiki, running on the same web server, with the same php configuration, that does not have this issue?

If so, that is quite odd. Do you have the same extensions installed on both (and specificly, do you have any captcha extensions installed, simply because they mess with how editing works, so that would be one of the first places I'd look [however, I've never heard of a captcha extension causing this sort of issue])? Are the MediaWiki instances the same versions?
