Our installation in our university uses php as cgi (not apache module).
And the url of the server is something like:
http://www2.ub.edu/optics/tiki (ftp uploading to the site www2.ub.edu), while the official url for visitors is
http://www.ub.edu/optics/tiki
So, after I click on the create resource (from the first domain), I'm directed to a wrong url (the second domain), by the way, saying that I don't have permission to see that resource, etc.. However, If I visit the right url, I can see that the resource has not been created.
