*sigh* At this point, as far as I can tell by the sheer number of people complaining since this summer, the best solution is to simply not use x10 hosting anymore.

(But I strongly assume whatever problem x10 has it's only impacting some, but not all, of their servers.)

About the only other thing we can do to help is to ask to see your
inc/config.php file to make sure it is configured correctly.
