Unable to set filesystem credentials...

Recommended Posts


Hello -- I recently upgraded to the latest DMS and WordPress, and I'm getting the error (that I've seen in other threads) about an ability of the DMS to write to an uploads directory in wp-content. I've confirmed that there is a wp-content/uploads/pagelines (which I created, as it wasn't there before) directory owned and writable by the apache user the the Web server runs as. I'm at a bit of a loss.


If it matters, it's a multisite install.


Here's my debug info:

Thanks for your help!

Hi there, do you have the pro tools plugin installed? This has some hacks installed which can help with these messages and multisite issues. Posix will apparently stop the css writing a static file, so the pro tools plugin will definitely help there as it has a bypass in it. Install that from your account page.


According to a thread our developer responded on the error message you're seeing display means "WordPress cannot get direct access to the filesystem, probably because the files username/group is different from the username/group that php/httpd is running under. There are a lot of ways to setup php to run as your username, really depends on how you installed php and the webserver..."


If you've manually added wp-content/uploads/pagelines/ then you'll need to change the file to run as the same username as the php/user and that the php/user has write access.

Kindly search the forum and read the documentation before posting. It will help you resolve many issues.

For CSS help be sure to check out W3Schools first and be sure to download FireBug for FireFox for troubleshooting.

Hi James -- thanks for responding!


I do have the DMS Professional Tools plugin v. 1.4.3 network activated -- should that be all I need?


I'm pretty sure my permissions are correct. Right now my apache instance is running as the apache user, and wp-content/uploads/pagelines is owned and writable by the apache user (and by the web group). I've confirmed that PHP is running as that user. I created the pagelines directory because it didn't exist, on the off chance that'd be necessary to get it working. Does multisite change where that pagelines directory need to be, somewhere in blogs.dir for example?

If it helps anyone, I figured this out. It's not enough that the Web server user have write access to your uploads/pagelines directory. The WordPress scripts themselves have to be owned by the same user as the Web server. Maybe that was really clear to everyone, but it wasn't for me. All's well now. Thanks!
