Hello, everyone.

I have my websites hosted on a shared server with apache serving all
customers by a hosting company.
The problem I am having is not able to delete my files/folder owned by
Apache "nobody" user. Some of these files are php cached files.
I could not chown to take ownership over the files. rm -rf won't work.

Can someone advise me on this?

Thanks.
