Problems accessing graph after patch attempt

[cactos]

I attempted to apply the available patches to cacti v0.8.7e and backed out of it by replacing updated files with the original files (made copies of the originals).

Now I can't get to any of my graphs...when I login, I get the message "Access Denied" and "You are not permitted to access this section of Cacti". In looking at the http error log, I see a bunch of messages:

[Mon Nov 16 14:34:46 2009] [error] [client x.x.x.x] PHP Warning: include_once(/usr/share/cacti/include/global_arrays.php) [<a href='function.include-once'>function.include-once</a>]: failed to open stream: Permi

and more lines like above about undefined variable. I do not see a problem with file permissions/ownership.

I would sure appreciate some help. I'm running it on Fedora 11.

Thanks!

Try performing the following, as root:

chcon -R --reference=</path/to/webroot> </path/to/cacti>

That fixed it, thank you!
