chat work only in local.

[freedom]

I have published the Php Free Chat at this address http://www.prova9999.altervista.org/index.php , but it doesn’t work. In local it is everything ok and on the same host the other users’ chat works perfectly.
Maybe the problem is caused by javascript, in fact looking at the console of the errors, appears a series of it.
Can someone help me?
thanks

Ah, you ran it in local first, then posted it? Clear your data/private/cache foldersand try again.

Thank for the answer. I've already clear this folder, but the chat don' work. I've see this file: http://www.prova9999.altervista.org/checkmd5.php and I think the problem is due to an incorrect upload of some files. I upload another times the files, but some of them remain incorrect.
I don't know what I've to do.
