Weird Font Colors suddenly appearing

[keress]

I've had a template theme up for the past year. My host changed servers in the past month. Intermittently I'm getting an odd font color, a bright yellow showing up for all linked text that's close to the color of the background, and therefore pretty unreadable. I've checked the template controls in my admin, and I see no yellow fonts anywhere. I've tried adding a tag to the Advanced User input box specifying the right color for linked text, but I'm still seeing the bright yellow.

I've grabbed a page view of the code being generated and put it into Dreamweaver. No yellow color showing, no yellow font color in the code.

What could be going on?
