Thread:Project:Support desk/Import page suddenly not working

Was doing fine, importing. Suddenly yesterday, I can no longer do it. It tries to connect, it says "waiting..." for my site to respond, then times out with "Problem loading page". Using Firefox browser: MediaWiki 	1.19.0 PHP 	5.2.17 (cgi) MySQL 	5.0.91mm-log

The site is otherwise accessible. I can move around in it ok. I am at a loss, just doing the same thing over and over again with the same result. Isn't that the definition of idiocy? Can anyone here point me to something?
