what's going on?

Have noticed that images are not showing up in some posts that have them. When I try to post one myself, all I get are these error messages;

Warning: move_uploaded_file(/gallery/photographyreview/5fd19859993a0e4dadde961f62169ff7): failed to open stream: No such file or directory in /data/data01/web/test/html/files/includes/functions_file.php on line 219

Can someone help on this???

I'm not sure what is causing this, but I know they were doing some maintenance on the forums last night.

Hope they can get it fixed soon. Someone said it may be the problems with the server.

I am finding it impossible to upload photos. At best, it took me a half dozen tries or so to get one photo to upload; now, I cannot get ANYTHING to go. I keep getting a "Thumbnail error 1" message. Being functionally computer illiterate, this technospeak means nothing to me. Frustrating process.
