Firefox can't find the file at /R/call/base/identity/json. I am running openCPU I can go to

127.0.0.1

it goes to 127.0.0.1/pages/

And then I go to the example API and I try out the buttons to run example codes and it tells me You dont have permission to access /r/pub/ggplot2/qplot/pdf

Also

There are several things that can cause this issue, your os setup might be too secure for example you are SELinux , you might have to chown or chmod the permissions on the file system, or you might have to reconfig apache itself.

Here are some resources to help solve the problem:

If you need to check file permisions: http://wiki.apache.org/httpd/13PermissionDenied and that demostrates how to use namei:

namei -m /usr/local/apache2/htdocs/foo/bar.html

To see what is going on.

This dicussses a solution for SELinux causing a problem with the apaceh permisssions:

Apache 403 error, (13)Permission denied: access to / denied, Fedora 16

Essesstiaally you apply chcon -t httpd_sys_content_t to every directory in the path to the document root.

Since you don't seem to be running cgi or php it probably isn't a problem with loosing those permissions, but if it is you should make the http.conf for apache allows executing scripts and that they are in an appropriate directory.
