Thanks Mike and Victor! It was the site_name variable (the move involved also changing the site name, since I had both sites up for a while, I guess, I messed it up!). <br>I used the variablecheck module. <br><br>Ursula<br>

<div></div>I moved my sites to a different host (aside: VPS makes a big 
difference over shared hosting!), and for one of the sites, I get this error
