* I’m getting the following messages within Quick Cache Pro, version 140725 :

* I have my /wp-content/cache/quickcache folder permissions set to 755. Any ideas
what’s up? I do have BulletProof Security installed, but don’t think that’s causing
this.
* Thanks

* Any ideas?
* Update – it seems like I get this error when manually clearing the cache, but
I can’t recreate it all of the time.

* Thank you for the bug report. I believe that I’ve found the reason this is occasionally
occurring. I’ve opened a bug report and will get this fixed for the next release:

* Looking at the error message a second time, I noticed a line that said “failed
to open stream: Stale NFS file handle”. Can you confirm that your hosting environment
is running an NFS (Network File System)?
* I have heard of issues with writing files to disk in such a hosting environment,
so while I do more research I wanted to confirm with you that you’re actually
running such a thing. 🙂
* Also, do you mind sharing what web host you’re using?

* Hi Raam – I’m using GoDaddy hosting. I called and asked about NFS, and they said
my hosting environment is not running NFS.
* Fortunately I haven’t had this error occur in a couple of days.

* Thanks for the info, Pete. I still suspect not using atomic file creation might
be to blame here (see the GitHub issue for details). I’ll fix that with the next
release and hopefully that will resolve your issue as well.

* No problem Raam –
Unfortunately I had another problem today, and am not sure
if it’s related or not. This time I’m pretty sure I did not manually clear the
cache. I realized that my wp-content/cache/ permissions were set (or possibly
reset) to 705, so I changed it to be 755 now. I do have the experimental HTML
compression enabled, and have all of the options set to ‘Yes’.

* That’s really a question for GoDaddy, as it will depend on the server setup (
which user runs the web server, etc.). All Quick Cache needs to operate correctly
is to have write access to the cache directory. I recommend asking GoDaddy support
what they recommend.
