I used mediawiki 1.2.0 on my Server and because of the php Version I cannot update it. The problem I have is that I can edit and save the page on the local machine. But, if I tried to edit and save pages using external computer, it will show up a connection reset error.
From external computer, I can view all the pages, create user account, even upload a large size of file.
Any suggestions about how can I DEBUG this problem?
