Plugin Installation not working

[slaith]

Whenever I try to install a plugin from within Wordpress admin interface, it says Plugin install failed. "Could not Create Directory. /". Now I understand how this might be a problem since / directory cannot be created. I looked in wp-config, and many other sources, could not find anything wrong. ABSPATH registers correctly, but this problem is still there

ScreenShot OF the Error

Did it work previously on this host?

Do you have to enter your FTP Credentials?

Do you have a 2.9.2 installation on the same host in the same style setup you can test?

If FTP, When you connect by FTP, what are the paths you see? Is WordPress installed in "/" when you connect by FTP, or something else such as /public_html/somehost.com/<WordPress files>

What path is ABSPATH set to?

Setting to Future Release pending confirmation of what the problem is.

Someone experienced this problem the other day and came to the #wordpress irc channel. The end result was that they did not have a directory called wp-content/upgrade

Creating this directory manually and making it writable to the webserver user resolved the issue.

Hm, That folder should be auto-created in all cases if it doesnt exist, I'll run a few tests to make sure thats still happening in edge-case environments shortly.

Done. There was no folder called upgrade. I made one and everything seems fine. Thanks Sivel. Also just for info, I wasn't asked for FTP credentials, ever, and this is a new install. Perhaps you should ship the folder in the distribution itself, instead of having it auto-created? Just a suggestion

(In [15156]) Do not check to see if parents of folders outside of the Destination folder exist within the Archive extractors, unzip_file() will take care of that area. Fixes #13741

...Cant fix something in the future...
