Hello, first of all forgive for the English!
My case is that I have commented the file as follows:
$ x = new wikipedia ('http://es.wikipedia.org/');
echo $ x-> get_page ('story', true);
I have it on a Apache server Ubutu. When I put in the file browser, does not show me anything, I gave the appropriate permissions to the directory where you stay.
The other files I have not touched, are as I have downloaded. Any suggestions? thanks
