Re: Weird permission issue


I think you can run through the following checklist:- 

1. Web server is running under the same user which owns that directory. 
2. If the owner is not the same, then please change the owner using chown .
3. If permissions are not the same, then change permission using chmod.
4. On some Linux boxes, SELinux may have been enabled, and context has been set for that specific directory. You can try to disable SELinux.  

Let us know if it works, if not, we can move ahead with other checklist items. 
Thanks and Regards

Yes, as I said in my pervious message I tried chown-ing all the dirs
to 777 but I still get the error.
