Weird Font Colors suddenly appearing
 

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?
