remove "in" from pages as displayed when clicking tags

I only noticed this since 3.1.2, but the word “in” appears on each of my pages as displayed after clicking a tag in my tag cloud. I want to remove it.

I’m running tagpages, a plugin that allows pages to be tagged, and I’ve killed the timestamp that appeared before the “in” using another plugin. It also showed the word “by” and the username a was logged in as when I created that page. I deleted that user and both “by” and the hyperlinked username disappeared.

The “in” remains. Is it looking for a nonexistant category or something?

I’m using tarski 2.6, so there’s no page.php file. I’ve looked all over but cant find it, but I am way over my head any time I look at code. Thanks in advance for your help.
