I am trying to upload some files to the lesson plan section.

I get the following error message.

400 Bad request. Your browser sent a request that this server could not understand. The file size is not very big.

This website is running very slowly for me, but I don't know if that is a factor.

Any ideas why it is not working?

I tried a .ppt and a .doc file.

I am using firefox to upload if that helps.

I can post without a problem but can't upload these files.
