ARGH!!! Where have these unwanted, un-needed staus messages come from (class="messages status")

I don't know where these have come from.

They occur in the same place and look the same as the usual admin status messages that inform one of certain state changes but they just contain "page_1" or nothing or some other unhelpful or unnecessary info.

See example code below. . .

<div class="messages status">
<pre>page_1</pre>
</div>

There are no classes or ids to distinguish which module is outputing this SUPER annoying bug.
I suspect it's coming from viewreference, since it seems to be happening mostly on pages where I use a viewreference.

Any help would be greatly apreciated.
I'm trying to launch this site by Wednesday morning.
I know I can stop the display of the messages using CSS but I'd rather know thje root of the problem and get it fixed
