... I suggest that you install some other browser and test with it.
Whenever I click "Edit this page" or create a new page in Wikipedia, I just download a PHP file and nothing else happens. I don't know if this is a browser problem or what. When I click on the section-wide "Edit" button, I get taken to the editing page. What can I do to prevent the file download and be able to actually edit an entire page or create a new one?
I'm currently using Safari 4 for mac.
Like I said, I don't know if this is a browser issue, if it is not, then can an admin move this to the proper forum?
