Hello Roddy,
I am also having a publishing problem. I would describe it almost the same as Silpisces77 has in his/her original post.
The difference is that I hadn't added anything to my site. I had opened iWeb to swap my temporary home page (announcing a temporary closure of my store) with my normal home page. I've done this hundreds of times.
But after doing the drag-n-drop swap, it wouldn't publish. All indications were that it was 'trying' to publish (as Slipisces77 had described).
I have contacted my host and verified that the files are intact upon the server.
It normally takes about 3 minutes to publish the site. I tried all week last week to fix this (repairing permissions, deleting preferences, etc) and thought that maybe over the weekend I'd just let it keep working (assuming it was doing something considering it tells me that it is when I try to quit). When I hit my desk this morning, nothing had changed.
As per your suggestion above, just now I tried publishing to a local folder. It won't.
I could try calling my host again and have them delete the whole site from the server and try publishing from scratch, but I don't want to pay for that quite yet ....
Any other suggestions?
Jordan.
